Method 1) 2 rubber balls were left sitting at room temperature, and 1.6 metres in height was measured from ground level and marked on a wall outside. Temperature Quadratic ANOVA, Table 10: Ball 2 vs. As long as there is stress, some molecular bonds will continue to reorient to less stressful positions given enough time. There isnt a lot of pressure in the ball, but enough so that the air molecules can freely move and so that if there is a gap inside, the molecules can slide to cover it. That means theres more water in the air, causing it to be and feel denser. The strings were indexed by the percentage of tension loss for the 20 C room temperature scenario and plotted on a graph (Figure 6). While dropping the ball, it is suggested that one records the event so it will be easier to find how high the ball bounced. 5.Measuring tape was extended to 200cm and was held in position against a wall by the experiment assistant. Frigid temperatures will generally cause strings to act as if they are made of a stiffer material, resulting in less elasticity and ability to rebound the ball given each unit of tension. Today there is said to be 25,000,000 bocce ball players in the United States. Is a Photograph equally sharp in all area? Two variables will be omitted in the study, how much the ball is played with and different court surfaces. Many things are better when aged, and I would like to know if this is also true for tennis balls. When the first two examples were done, I noticed that there was a slight trend between the ending pressures as the temperatures decreased. It is common knowledge that most strings lose a large percentage of tension with time and play. Its essential to store rackets at room temperature and in non-moist environments to minimize breakdown of the strings and to extend their working life. Tension and temperature drop was then recorded until 100 seconds. Its also worth noting some of the less short-term effects on racket stringing. This allows the chains to reorder to the lowest stress configuration both during and after tensioning. Stiffness and elongation are proportional to temperature, though the effect is not great. The pressure of the gas inside the ball ultimately determines how high the tennis ball will bounce. (2012, 8 22). Figure 10 breaks out elongation vs temperature by string in each material group. Then they would be dropped from a table, and the height would be measured. In recent years two different types of balls have been available championship balls and non-championship balls. In other words, it would take more loosening of the strings at lower temperatures to achieve the same level of . Purpose The purpose of this project is to determine how tennis balls are affected by different temperature conditions. (Borlings, 2011)They did not bounce very well, however. The amount is highly material specific, with gut, nylon, and polyester losing the least tension in that order. The balls need to have the right temperature and air pressure inside in order to work best. This time, the ball can be heated for longer than 20 minutes. This is the table showing the heights in which the ball bounced. Place the tape measurer against the edge of a wall using the bluetack 3. As bonds break and reorient, tension decreases. The main. The temperature of the ball affects the elasticity of the material of the ball.

Does the Temperature of a Basketball Affect the Bounce of the Ball? Retrieved 8 24, 2012, from Wikipedia: http://en.wikipedia.org/wiki/Tennis_ball, Your email address will not be published. Why Is String Stiffness So Important To Power? This is expected. With this, it will look at the movements that occur at each of the upper extremity together with the muscles that are in use at the joints. Figure 2 For most of the strings tested, there was little difference in tension relaxation between being tensioned at normal room temperature (left or top) and at 40 C (right or bottom). As you will notice from your experiment, the balls that have been treated to the ice chest with ice in it will tend to have lower bounces, resulting from the molecules moving around less and containing less energy. The hypothesis was confirmed as the room. the serves comes in five main types of which includes; cannonball or flat serve, topspin-slice serve, slice serve, American twist serve and the topspin serve. Now the equilibrium between the tension and the bonds is broken. Why don't you do an experiment. Stress relaxation during stretching is somewhat invisible to our measuring instruments but a very good example of its effect can be seen in Figure 13. In the experiment only a hard surface will be analyzed and no playing with the ball will be allowed. The setup was essentially the same as in Figure 1 but a computer controlled stretching program was different. When a ball drops gravity pulls it down to the ground. Place one of the balls in the freezer for 30 minutes (you can do this while executing steps 9-14). A thousand seconds after achieving target tension and being clamped off, the string that took only 1 second to stretch to target tension lost almost 3 Kg more tension than the one that took 26 seconds. Tennis balls are typically air-conditioned and have internal air pressure that influences their bounce. Ever felt that muggy feeling when it is particularly humid outside? Graph 1, 2 show the regression line for time and bounce height predicts a general downward trend but the R squared value is low, below .17 in both cases. Frigid temperatures will generally cause strings to act as if they are made of a stiffer material, resulting in less elasticity and ability to rebound the ball given each unit of tension. What players feel when hitting in various temperature conditions is the combined effect. As the molecules expand, their energy increases as they bounce around more erratically. At 200 seconds, the string was heated to 40 C. This took about 100 seconds. That is precisely what happened in the experiment. During fast volley bouts your muscles often react. Percentages of the tennis balls bounce. Heating before tensioning would simulate the effect of temperature during the stringing/tensioning process. It wasn't much less and one might be tempted to say that for practical purposes there was no difference. Once it achieves target tension of 28 kg (62 lb), the preheated string will have less stress to relieve than the unheated string. A good example of this would be, when designing buildings to survive in areas where earthquakes happen frequently. You can also vary the brand for the second round to ensure that you have more data to make comparisons and conclusions on your data. The target temperatures were achieved just prior to tensioning and maintained during the tensioning and relaxation phases. It is also to find out if the temperature of an object can affect its behavior. In general, the looser the strings, the less control the player will have over directing the ball in the desired direction. Temperature is either something that is cold or hot. Drop ball and mark where the lowest part of the ball is after the first bounce. Fourteen strings were tested: 1 gut, 1 kevlar, 7 nylon, 5 polyester. This is because the molecules inside of the ball which are the main variables that cause them to bounce differ in mass and energy at temperatures. It will, however, continue to equalize stress after tensioning more quickly than the unheated string, so will lose a bit more tension than the unheated string. The string ends extended past the end of the tube and were clamped. As an experiment, you can try to heat a tennis ball and see how well it will bounce. The stiffness tests closely approximated the expected result that stiffness would have an inverse relationship to increase in temperature. Once the arm has begun to accelerate towards the ball, the tricep brachii is then used to, The ball uses this kinetic energy to move up the usually 6 to 7 degree incline to the top of the playing field. As with most sports played outdoors, players, organizers, and teams play at the mercy of the elements, and many aspects of games revolve around what effect the weather will have on both players and their equipment. The string was then allowed to cool for 200 additional seconds. In the study, they considered strings of different materials under different temperatures. The tennis balls which were placed in a boiling environment had an average bounce percentage of 83.33. Repeat steps 1-3 but keep the ball in a refrigerator. So, in the stretch phase, colder strings elongate less and provide less time for the molecular bonds to respond to the stress caused by the stretch. Gas molecules are generally unorganized; they easily slide around and over one another to fill up any space they occupy. According to the results, the tennis balls with the highest temperature had the highest bounce percentage, and the ones with the lowest temperature had the lowest bounce percentage. The scientific equation for determining the pressure of gas is p=rRT, where p is the pressure, r is the density, R is a constant specific to the gas and T is temperature. Table 9: Ball 1 vs. Top "The Effect of Temperature on a Bouncing Ball." The Effect of Temperature on a Bouncing Ball. Tape measure The ball will not bounce as much in the cold as it does during hot days, and for the players, this is a vast difference that is also evident in how they take on the matches at different times. The kinetic, Tennis is a game of speed and reflex. Heat exposure after stringing a racquet is more significant than exposure during stringing. Here is a diagram of the structure of a tennis ball. Controlled variables: Refrigerator/freezer stopsworking, there is no heat source, room temperature is extremely hot, video camera has bad graphics and one cannot clearly see things recorded, height from which the ball is dropped. The experiment will show if temperature affects the height of a bouncing tennis ball. For example a tennis ball will bounce higher than a soccer ball because it has more air pressure and it is harder. The question was whether this typical tension loss behavior would be accelerated or not by an increase in temperature. With an increase in the temperature, the gas molecules within the tennis ball start to expand. This scientific mystery can be demonstrated at home or school with a simple experiment. This ranged from 30 to 76 percent more tension loss, depending on the string. The anatomy of a tennis ball features a hollow rubber-like core filled with gas. When the ball is still very new, there is usually a lot of air inside it. By using a 1 meter ruler to measure the bounce height in centimeters. The first setup (Figure 1) was used to measure tension vs time for strings with different temperature exposure histories. For this reason, you will often notice that the players performance during the summer is different from their performance in winter. Temperature were Plotted in 15, 16 both again show similar patterns indicating a upward trend in the data and poor randomness, both would be considered poor indications of a good fit. Once you have the right conditions under which to carry out your experiment, you can go ahead and start gathering the materials that will be needed. Tension loss by temperature is shown in Figure 11. Have another person measure and record how high the ball bounces.

Put 2 in the freezer, also for 10 mins, so they can First, make a way for the ball to drop from the same height every time. Tennis balls in the 1400s were quite similar to the first tennis balls, butthey were stuffed with chalk, sand, sawdust, or earth. In the heat, the molecules are more active, so the ball can bounce higher, and in the cold, the molecules are heavier and have less energy, creating a smaller bounce. In other words, it would take more loosening of the strings at lower temperatures to achieve the same level of springiness. The ball will depress and rebound off the strings less efficiently in cold weather; therefore, it takes the strings being looser to achieve the same level of elasticity that would typically be possible at warmer temperatures. Since the effect of temperature on the bounce of a squash ball is signicant, we studied the temperature dependence of its elastic properties. Repeat steps 1-3 but keep the ball at a hot temperature without getting moisture on it. After the ball hits the floor the ball gains motion that is. The part of a paintball gun that is used to shoot the ball accurately is the barrel. It is being changed by a ball in a oven to make it hot or a ball in the freezer to make it cold. How does temperature affect the bounce of a tennis ball? The higher the percentage, the higher the ball bounced. The relatively uncontrollable nature of weather presents a variety of challenges to address to perform at the highest levels. The scientific equation for determining the pressure of gas is p=rRT, where p is the pressure, r is the density, R is a constant specific to the gas and T is temperature. Their central finding was that tennis string is affected by temperature, but not always in the way that one might expect. Retrieved 8 24, 2012, from LIVESTRONG: http://www.livestrong.com/article/398740-temperatures-tennis-balls/, Incorporation, I. Tests with this apparatus were conducted at 20 C and 40 C. 20 C was room temperature with air conditioning. It is the interplay between stretch rate, stretch amount, stretch duration, temperature, and stress relaxation that effects the amount of tension loss that occurs only in the relaxation period (the period that was measured to get "tension loss"). You can also change how a ball bounces by changing its temperature. (Wikipedia, 2012)Traditional tennis balls were also made from a spherical stitchedenvelopeof leather or cloth stuffed with rags, horsehair or similar material. This type of heating has a permanent effect. For the cold ball, you are likely to observe a lower bounce consistently. When a tennis ball hits the ground, the force presses up against the ball, pushing the bottom surface of the ball in and compressing the gas inside its core. Create a free website or blog at WordPress.com. The thing that is changing is the temperature of the tennis ball. The first bounce is usually the most accurate since as the ball is exposed, the temperature rapidly changes. So, for the most part, adapting to weather or other environmental conditions can usually be done relatively quickly. (Borlings, 2011)The game is outdated and is not played anymore. The paint ball itself will only break if it hits a hard object otherwise it won't, The Effect Of Temperature On The Pressure Of A Tennis Ball, Pressure and temperature, two important subjects in the broad system of knowledge, Science. I did notice a different in weight. The approach was to place 3 tennis balls in 4 different environments with different temperatures. But if heat exposure occurs after tensioning and stabilization, the molecules become agitated and begin to move relative to each other. When a tennis balls temperature changes, the balls gas-filled core undergoes an interesting reaction. You can get an idea of just how much by looking at the percentage difference in stiffness resulting from the temperature exposures. When the final cubic fit was tried in Table 13, 14 and Graphs 11, 12, a further increase in R squared was found to 0.979 and 0.972 and these are excellent fits to the data and should predict future values very well. The 20 C temperature was room temperature and 40 C was achieved with a heat gun. co2 is carbon dioxide and carbon dioxide is an expanding gas. This machine measured string tension vs elongation. Aim: The aim of this experiment is to see which ball is better quality for bouncing and what is a lot more reasonable for price and size. Tennis balls were first made in the early 1300s. Your email address will not be published. Take 2 tennis balls and put them in the slow cooker for 10 mins. Equilibrium occurs when all molecular bond attractions are greater than the tension trying to tear them apart. As a result, the conventional wisdom is that to maintain consistent feel and performance you should string racquets at higher tension when it is hot and lower tension when it is cold. This is due, in large part, to their construction. Tennis ball. Ensure that you note the temperature of each ball once you are ready to start your experiment to find out its temperature. I should also research to determine who should not use a stability ball. i was just worried even if they are correct or not. My daughter is in the 5th grade and she is doing this experiment. Ball History. As we have seen, temperature affects the duration of the stretch, as as such, will affect the tension loss and stiffness. (Borlings, 2011)However, in 1470, Louis XI of Franceforbade the filling of tennis balls and said that they should be filled with high-quality leather. The colder, the lower the ball bounces, and vice versa. This means that the hypothesis was supported because it stated that if the uniform temperature of a tennis ball is increased, then it will bounce higher. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Enter your email address to follow this blog and receive notifications of new posts by email. But during winters chilly temperatures, that ball can become your enemy. This will give you a visual presentation of the bounce heights and the temperatures, which means that determining whether hot or cold balls can bounce to a higher height will be a lot easier. Tennis serve is the shot that starts off the point. When a tennis ball is compressed, its internal air pressure is boosted. History Of Tennis Balls Who Invented The Tennis Ball? Place DrDAQ on the floor and configure it to measure the "sound level" with a sampling rate of 10 ms Start recording the sound level. Molecules of a gas can effortlessly expand and contract. Sometimes, new balls might give you different results than older balls which means that your experiment will require a new source of data to determine whether you are getting accurate results. Temperature Quadratic ANOVA, Table 13: Ball 1 vs. Experiment. Hold the meter stick vertically with one end on the ground. Most balls use valves for air retention. Tension Loss. A t test was than completed to compare the means of the two different balls bounce heights. The higher the pressure, the more the ball will bounce, and vice versa. The deltoids and pectorals major are used to flex the shoulder. Two different types of balls, Penn Championship and Non-Championship will be compared. Figure 8 presents just such a picture grouped by materials. Hypothesis: The normal tennis ball will bounce higher than the tennis ball that was placed in the freezer for some time as the air molecule inside are not affected but for the cool tennis ball its air is compressed affecting its bounce. The question of concern was whether adding heat after stabilization would start (or accelerate) tension loss. This is longer than the 5-8 ms ball bounce from a solid surface or racquet. A warmer ball will bounce higher than a cold one. Record temperature on the thermometer of the ball and write it down. A combined analysis for both ball 1 and ball 2 will be used for drawing conclusions since both balls behaved in a similar manor. If a 82,37,and 70 degree tennis ball are dropped,then the 82 degree tennis ball will bounce the highest because the molecules in the 82 degree tennis ball will move faster. Borlings, D. (2011). Hot temperatures create more pressure whereas cold temperatures do not produce much pressure. In general, players can compensate by adjusting playing style as well as making technical tweaks to their rackets and stringing configurations. very interesting.Amazing amount of detail. For ball 1 a value of 0.925 was found and 0.908 was found for ball 2. Record the temperature on the thermometer. The bladders are usually made of rubber or rubber like things. The conclusion for the two different ball types will show which is in fact is a better ball in each of the different situations. Overall the residual plots show that the fit is good, but there is some considerable doubt and, it is possible another model might fit the data even better. It is the other way around for polyester the 20 string loses more tension than the 40 string. These acquired values show that the line is a good predictor of future points and where they will fall. One may also use a heat dish to do this. Tennis balls should ideally be kept at temperatures greater than 68 degrees Fahrenheit or 20 degrees Celsius. The temperature regression was carried out last. The molecules that make up gas are relatively unorganized; they readily slide around and over one another to fill up any space they occupy. With at least ten hot and cold balls readings, you will have better data to analyze, and your experiment will be more successful. And we saw in Figures 7 and 8 that stiffness is proportional to temperature. Sealable plastic bags Jeu de Paume was played without even bouncing the balland was just played against a wall. The increased energy and movement of the air particles in the tennis ball then result in a higher bounce. Results for Setup #2 ‐ Elongation, Tension and Stiffness vs Temperature. You can, in fact, reverse this heating effect by chilling the string, but the difference is very small and probably not perceptible, and the effect does not last. Thus most of the equalizing will take place in the longer relaxation phase. A good source of heat that can heat things evenly. Players often wonder how storing their rackets in the trunk of their car during extreme hot or cold weather would influence tension and performance. Most players focus on tension, but that is only useful in as much as it predicts stiffness, which is often the case for comparing an individual string at different tensions but not for comparing different strings to each other. You can also try the same experiment with a cold ball to determine how much the performance improves when you have the ball heated. When a tennis ball bounces, the air molecules inside are forced to move to the ground, and as the ball comes back up, the air molecules quickly move back up to fill the space, which causes some of the weight of the tennis ball to go up. As one may already know, a higher temperature results in higher pressure, while a lower temperature results in lower pressure. Retrieved 8 24, 2012, from ITF Tennis: http://www.itftennis.com/technical/equipment/balls/history.asp, Sheehan, K. (2011, March 11). Higher temperature allows weak secondary bonds between the polymer chains to break. What is happening? By far the cubic fit is the best out of the three regression models analyzed but the R squared values are all well below 0.9 which is what would be needed as a minimum to make the models good predictors for future trials. Analyze the data, and make a conclusion stating if the temperature of a tennis ball affects how high it bounces. Figure 3 shows a typical result for this process. Mark a point 1 metre from the ground on a wall. For the sake of our experiment today, you will need to have a concrete floor or other hard surfaces that will be used to perform the bouncing test. . Hot temperatures create more pressure whereas cold temperatures do not produce much pressure. The distance between clamps was 35 cm. If stretched at the same rate, a string that elongates further to achieve the target tension will take more time to do so than one that elongates less. A further study should be completed to see if anything else effects the balls differently to try and determine what makes the balls different. Hi my name is Charly i was doing this project and i did`n know how to do this. This is because the gas molecules inside the ball expand . The courts are designed so that the ball can bounce off any surface and still be in play, yet it is in a confined area so you don't have to run to cover too much territory. This allows more elongation at lower stresses than occur at lower temperatures. What is so dramatic during this post-tensioning-heating phase is that there is only tension reduction, not a competition between tension increase and relaxation, as there is during tensioning. I thank Dr. Choi for teaching me how to do this assignment and my parents for buying tennis balls for me. For this reason, the players will have a better experience which is usually caused by the plenty of pressure inside the tennis ball. Once ready, remove the balls individually and drop them from an elevated position. Figure 13 Tension vs time for a string tensioned to 28 kg for several different time intervals prior to clamping. And according to the experimenters, tension is, in reality, a determinant of stiffness. Temperature can be measured by. (Borlings, 2011) From the 1920s, the process of making a tennis ball was based on the clover-leaf principlewhere a sheet of rubber was shaped into a three-leaf clover. Retrieved 8 24, 2012, from How 2 Tennis: http://www.how-2-tennis.com/history-of-tennis-balls.html, Harriman, D. (2012, 7 24). As such, gas molecules can easily expand or contract. A string was inserted inside clear perspex tube with two open ends and through a small hole in a rubber stopper at each end of the tube. If the uniform temperature of a tennis ball is decreased, the balls bounce will be lower. Stress relaxation occurs both during and after stretching. (Incorporation, 2011)In the late 1920s, tennis balls became pressurized. This isnt something that you can control. The air molecules inside the ball will also move around slowly and tend to have less energy when the ball has been cooled down, meaning that the ball will have a lower bounce when you drop it to the ground. The strings were each given an Identification number from 1-15 (14 was omitted). Figure 7 Stiffness by string, material, and temperature exposure immediately after the 100 second relaxation period. Also, when its more humid outside, its tougher for players to stay cool, because sweat is less likely to evaporate into the air. As the tennis ball returns to its normal shape, the gas inside the ball acts as a spring and causes the ball to bounce into the air. (Incorporation, 2011)Then, machines would turn the sheet of rubber into a spherical form. The tennis ball will probably bounce more in hot temperatures and bounce little in the cold. Bocce ball was steadily rising and falling in popularity, until a major resurgence in 1896, when it was admitted an olympic sport, and has been part of the summer olympics ever since. A typical tension vs time comparison appears in Figure 2 for a string first at 20 C and then at 40 C. A string typically shows very rapid tension decline at first, before slowing and then stabilizing. It uses a lot of muscle memory. Figure 3 Tension vs time for the same string as Figure 2 but following the heating-after-tensioning protocol. Six tennis balls As the tennis ball returns to its normal shape after getting pressed, the gas inside the ball quickly occupies the space that was open during impact which causes the gas to act as a spring, making the ball bounce into the air. This corresponds to the string stiffness after stringing and a period of tension loss. This reordering occurs during both the stretching and post-stretching phases. Tension loss in itself is a misleading parameter because it is part of the larger concept of stress relaxation.
