Investigating the Bounce of a Squash Ball
This investigation is associated with the bounce of a squash ball. I
will be investigating 4 different types of squash balls, which have
different, bounce properties and compare them to each other and relate
them to why each different type of squash ball is used. The
relationship will be associated with how different balls are used at
different levels of proficiency in the game of squash i.e. the squash
balls that don't bounce much will probably used at a less proficient
level whereas the balls with the most bounce will be used at
professional level. The different coloured squash balls I will be
using are; white, yellow, red and blue, and I will be finding out what
the difference is between them.

Pressure
The three scientists Boyle, Amontons and Charles investigated the
relationship between gas, volume and temperature. Boyle discovered
that for a fixed mass of gas at constant temperature, the pressure is
inversely proportional to its volume. So in equation form this is:
pV = constant if T is constant
Amontons discovered that for a fixed mass of gas at constant volume,
the pressure is proportional to the Kelvin temperature. So in equation
form this is:
p µ T if V is constant

Charles discovered that for a fixed mass of gas at constant pressure,
the volume is proportional to the Kelvin temperature. So in equation
form this is:
V µ T if p is constant.
The Equation Of State
These three gas laws that were proposed by Boyle, Amontons and Charles
can be summarised as follows:
For a fixed mass of gas
pV = constant if T = constant (i)
p/T = constant if V = constant (ii)
V/T = constant if p = constant (iii)
It was learned that changing the volume of the same substance will never change the boiling point of the substance. However having two different substances with the same volume will result in two different boiling points. The purpose of this lab was to determine if changing the volume of a substance will change the boiling point. This is useful to know in real life because if someone wanted to boil water to make pasta and did not know how much water to
I decided to use one type of ball, so the weight was constant. And the
Many people might think that swinging the bat straight through the ball would be enough to hit the ball a decent distance off the bat. There's many more mechanics involved in the swinging process. Muscle has only a small part to play in the swinging a bat for power. There are two types of mechanics involved while swinging a bat, Linear and Rotational. Rotational mechanics are the dominant source of power in the swing. Out of the rotational mechanics come the two forces that help generate the speed and power of the swing, torque and the other comes from the energy of rotation. Speed from the energy of rotation comes from the path that your hands follow as you swing the bat. The speed generated by the circular rotation from your hands is like a ball at the end of a string, as long as your hands are moving in a circle then the ball continues to accelerate in a circle. So the bat will also move in at an increasing speed as long as your hands are following a circular path as you swing. Any foward movement of the hands or body in a straight line won't add to the overall bat speed.
When looking at a collision between a baseball bat and ball, three things always apply:
Baseball is a fascinating sport that is exceptionally fun to play. This assignment is all about understanding the physics of a few key aspects of this sport. One might ask what physics could have to do with baseball? Like most sports baseball involves physical motion. Baseball encompasses all three planes of motion through throwing, hitting, and fielding. All of the classical laws of mechanics can be applied to understand the physics of this game.

Baseball is considered America’s past time. Legends like Babe Ruth, Lou Gehrig, Jackie Robinson, and many more have come and gone. Throughout baseball’s history certain players have excelled more than others, and like any sport they were successful by exploiting their strengths. It isn’t the rules, uniforms, stadiums, and fan base that make baseball a beautiful sport; it’s the players. Anyone competing, whether it is at a professional level or not, has their own unique mechanics that allows them to perform the best they can. No pitcher throws the ball the same way as another and no batter hits the ball the same way as another. Every baseball player has a routine in everything they do that makes them special. It has been said that hitting a baseball is the hardest task in all of sports. To accomplish that task, all factors come in to play; the type of pitch being thrown, the release point of the pitch, the break of the ball, etc. All those factors occur before the batter’s swing is fully initiated. As mentioned earlier, no batter swings the same way as another however, the mechanics of a swing is a different thing entirely. The mechanics of one’s swing begins when a batter enters the box and ends when a batter exits, what happens in between is up to the batter. By perfecting a batter’s mechanics while in the box, their chances of making contact increase greatly.
5. In a gas increasing the pressure means molecules are more squashed up together, so there will be more collisions. My Investigation. I am going to investigate the concentration variable. I have chosen this because in my opinion it will be the easiest one to measure.

The more and more I look around I begin to see how physics are integrated into practically everything that we do. These things would surely go unnoticed without making a conscious effort to notice them. For example simple things like riding a bike, or driving a car, or playing catch with a son or daughter. Just as these activities are loaded with elements of physics, sports are also, especially basketball. Physics play a part in every aspect of the game, from dribbling, passing, and shooting, to things as simple as setting a screen. First we should take a look at the elements of dribbling.
...the more energy is lost and the less the ball bounces back. The less denting that occurs, the more energy is kept and the higher the ball bounces back.
In conclusion, the height of a ball’s bounce has a lot to do with the surface on which it is bouncing. The harder the surface, the less energy is absorbed from the ball, causing the ball to bounce higher. The softer the surface, the more energy is absorbed from the ball, causing the ball to bounce lower.
Quantitative measurements on gases were first made in a rational manner by the English chemist Robert Boyle (1627 - 1691). The instruments used by Boyle to measure pressure were two: the manometer, which measures differences in pressure, and the barometer, which measures the total pressure of the atmosphere.
