Aim: The aim of this experiment was to calculate and compare the energy efficiency of bouncing balls.

Hypothesis: I predict that the soft balls will bounce higher than all of the other balls because they will be springier.

Independent Variable: The independent variables in this experiment are the type of balls. There are 10 different types of balls in this experiment.

Dependent Variable: The dependent variables in this experiment are the bounce height of the balls and the bounce efficiency of the balls.

Constant Factors: The constant factors in this experiment are the height from which the balls are dropped, the surface on which the ball was bounced upon and the velocity, which is dependent on the distance travelled and gravity, both of …show more content…

The ability to be compressed, the elasticity, the size, the weight, the material the ball is made from, the air pressure inside the ball, the temperature of the ball, the hardness and softness of the ball and the surface it is bounced on. The material of a ball can greatly influence the bounce. The bounce of balls with an outer covering, such as tennis balls and basketballs, will change over time. The surface on which they are played on gradually wears off the outer covering, changing the mass and the shape of the ball, therefore changing the bounce. Certain materials, such as rubber, produce a high bounce. This is because rubber is very elastic. Elasticity is the ability for an object to return to its original shape after being stretched or compressed. Elasticity is required because when a ball bounces, it is distorted into a more elliptical shape. Balls with high elasticity will create more elastic potential energy from the compressed ball. The ability for the balls to be compressed is important because without compression, the balls cannot create the elastic potential energy. The elastic potential energy is converted into kinetic energy when the ball bounces up again. The surfaces on which balls are bounced are also important. Harder surfaces will produce higher bounces than soft surfaces such as carpet or grass. In our experiment, we were bouncing balls on hard concrete tiles. The temperature also affects

However, they may have different amounts of it when they both bounce because of the way they are made. One’s rubber may be stretched or compressed in a way that gives it more elasticity or bounce so that when it hits the racquet or court it bounces higher. Tennis balls have less elastic energy than golf balls so one may think they have less elastic potential energy than racquetballs on average. Also, with the tennis ball weighing more and still having enough elastic energy to bounce as high as the lighter racquetball it is right to say that the tennis ball has more elastic potential energy. Finally, gravitational energy is the last main type of energy that affects tennis.

Some balls nower days are made the same way but they are very expensive. the “Haskell” performed better than the “gutty” and was way cheaper to make. Initially these surface moldings took the form of grooves (which we have on the golf ball today) and later bumps. The "bump" design was known as the bramble pattern, due to a resemblance of a blackberry. In 1910, balls with small dimples were made.

Data Analysis The scientific question that was asked in this experiment was,”What is the best angle to shoot a paintball to achieve the farthest distance possible?” The hypothesis of the experiment was,” If a paintball is shot at a 50 degree angle, than the paintball will travel the farther than any other angle tested.” The independent variable is the angle of degrees the paintball is shot from and the dependent variable is the distance the paintball travels at the different angles it is shot from. The control variables are the brand of paintball gun, the model of the paintball gun, the type of paintballs being shot from the paintball gun, and the tools used to measure the distance the paintball goes.

How does temperature affect the bounce of a tennis ball My science fair project is about tennis balls and temperature. I chose this topic because I am interested in how temperature affects how high a tennis ball bounces. When the ball hits the floor it expands and when it comes up then it comes back up it contrasts. My question that is going to be answered is,how does temperature affect the bounce of a tennis ball?

1. Much of Norah Fry’s work was accomplished as she determined to counter negative perceptions many of her contemporaries had about PWD. Identify and briefly discuss how PWD were thought to be either economic or moral failures during Norah Fry’s time. During Fry’s time, PWD were considered to be failures because they were not able to contribute to society since they weren’t efficient.

The null hypothesis of this research is that the gases (helium, nitrogen, argon, and CO2) will have no effect on the football hang time. This study’s alternate hypothesis is if a football is filled with a gas lighter than air (helium and nitrogen), then the football will have a longer hang time; and if a football is filled with a gas heavier than air (argon and CO2), then the football will have a shorter hang time. Since the first experiment results were nullified because of an error in the PSI of the football, the second experiment results led the researcher to reject the null hypothesis. There is enough evidence to support that footballs filled with gases lighter than air will have a longer hang time and footballs filled with gas heavier than air will have a shorter hang time. The reason to make this claim is that the researcher found that gases lighter than air (helium and nitrogen) had longer mean hang times and gases heavier than air had shorter mean hang times in Table 2 and because of the error bars in Graph 2, it showed significant differences between the means.

Now if it is of a lower-quality then it might be made with cork or rubber or even a bit of both. These materials are a bit softer as to limit injury. And last but not least a line of kapok is wound tightly around the center of the core to ensure that every ball is of 12 inches. http://www.ehow.com/facts_5407786_materials-used-make-softballs_.html

In the data, one trend found was that as the ball became closer to the ground, it’s kinetic energy value went up and the GPE value went down. Also, when the ball went up, the value of kinetic energy became smaller and the value of GPE became greater. This is correct because when any object is close to the ground the kinetic energy is greater than the GPE and when the object is at it’s highest point the GPE is greater and the kinetic energy is less. Another trend was when the ball was at the very end or beginning the total energy was .5 off from the total energies of the points in the middle. This is an example of inherent error because there was no way for the LabQuest to get the exact point and motion, so the calculations were bound to be

CHAPTER: (1) Introduction 1.1 Problem Summary and Introduction: The goal for our group is to design a ping pong ball launcher. The launcher needs to be scheduled to launch one solo ping pong ball one at a time over a set obstacle and into a bucket of a chosen diameter. The determination is for the launcher to have the capability to launch five ping pong balls one at a time into the container within one minute, having none of the ping pong balls bounce out or miss the bucket. The launcher can be made out of any matter preferred and can launch the ping pong ball in any anticipated way, except by explosion.

When a ball is dropped it bounces; usually returning back to the original height from where it was first dropped. Science refers to this mass of movement as kinetic energy. Kinetic energy allows the ball to keep moving. As long as the ball is moving some form of energy amount is present. I was asked to take a look; via YouTube; at this 28 minute long video of multicolored balls bouncing in a slow to medium speed along with slow relaxing music playing in the background.

The hypothesis for this project was “If a soccer ball has less regulation air pressure, then the distance the ball travels when kicked will be less.” It was therefore rejected. The soccer ball with less air traveled farther than the soccer ball with more air. The average distance of the soccer ball with less air traveled 29 yards, and the soccer ball wind or that I was tired.with more air traveled at an average distance of 19 yards. could’ve been caused by the It Everything went according to plan except that the hypothesis was rejected.

There is Plastic, Urethane, Reactive Resin, and Particle. The huge difference with the type of coverstock is it performance and how it reacts on the lane. When the ball is thrown down the lane it will it creates friction with the surface of the lane. The most friction created the greater the chance the ball will curve or hook. The amount of friction created depends on the coverstock of the bowling ball.
