History Of Charles Goodyear: The First Soccer Ball

For example a tennis ball will bounce higher than a soccer ball because it has more air pressure and it is harder.

This soccer science fair project serves to acquaint students with basic information on how the amount of air in a soccer ball can affect the distance it travels when kicked with a consistent force. The greater the air pressure in the ball, the farther it will travel when a force is applied. In the process of conducting the research, the student will learn that atmospheric pressure may also affect how far the ball will travel. The student will learn about the relationship between air pressure and friction: the lower the friction, the farther the ball will go. The student will learn about concepts like air pressure, gravitational force, compression and expansion of air molecules, potential energy and kinetic energy. This science fair experiment

The game that America has come to know and love may have more behind it than everyday viewers and fans realize. Physics fuels every aspect of the game of football and is evident in the collisions that take place on every play. Watching a game of football can be a great learning tool to anyone interested in better understanding the laws of physics. Many great examples are provided on every snap. Mass, force, momentum, velocity and torque all play significant roles in the tackling action performed by players and the better you understand these terms the better you can begin to understand the game itself.

“Force is defined as an object that has the capacity to cause change in motion” (McLester & St.Pierre, 2008,. 93).

The fastest growing sport in America is lacrosse, and in order to play lacrosse, it is important to first understand the physics of the game. Lacrosse players around the world use physics while playing without even thinking about it. With no knowledge of physics, it would be pretty difficult to master the fastest game on two feet. One of the worlds greatest scientist, Isaac Newton, established three laws dealing with physics, and using these laws will make it possible for a lacrosse player to understand what he or she needs to do in order to throw a ball. Newtons first law deals with inertia, his second law deals with the relationship between mass, acceleration and force, and his third law deals with opposite reactions. When talking about lacrosse, it is essential to cover Newton’s first law, his second law, and his third law in order to understand the physics behind throwing a lacrosse ball. .

The physics involved in soccer includes friction, torque, center of gravity, Magnus Effect and Newton’s three laws of motion. The physics of soccer comes from three main parts of physics which is velocity, acceleration, and displacement. Velocity is shown in soccer with the speed and direction of the soccer ball when it is hit or kicked. Acceleration is shown in soccer when the ball changes velocity when it is hit or kicked. Displacement is the change in position of the soccer ball.

where max power could be produced. Then “critical instant”, where the ball is pushed with great

An early painting from the Song Dynasty period shows the Chinese emperor and some high-ranking officials playing cuju with a ball that looks very similar to the one used in modern soccer. It has pentagonal-shaped pieces of processed ox hide sewn together from the inside. Another piece of evidence is a painting from the Tang Dynasty; it shows noble ladies playing cuju with a ball made with pieces of leather. “These balls were solid, stuffed with animal hair, and served the same purpose as the modern-day soccer ball,” explained the museum

In this literacy task I chose the soccer one. The prompt says that the ball was being kicked by three players and it describes the laws of newton. At first the ball was sitting in the middle of the field until the referee blew the whistle. The newton law used there was the first law because the ball was doing nothing.when the referee whistled Hugo kicked to ball straight to Juan and the newton's law used was 1 and the 2 laws. After Hugo kicked it, Juan kicked it to Michael. The law used there was second law. By the time the ball got to Michael the ball has some water from the grass on it. Michael kicks the ball with more force because it gets heavier with water on it. When he kicks it he is using the 3 law. The ball keeps on going on till another

The distance that you are able to kick the ball can be summed up with the equation for distance, d=RT, distance equals rate multiplied by the time. So speed and time are both very important when kicking the ball because it directly affects the distance. Soccer players vary the distances that they want to kick the ball. Skilled players can estimate very quickly how fast to make the ball move to make it go where they need it to. Before learning this equation in physics I just thought you kicked the ball, but now I know that when this equation is applied to soccer it means so much more. Soccer players can use this to help them judge how hard and fast they need to be able to kick the ball to make it go a certain distance. This is just another example of how physics, the small details, can be used to improve ones soccer skills.

Newton’s 1st Law states that “…An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted unless acted upon by another force.” For example, if you were in space and took your gum out of your mouth and threw it, it would never stop because in space there are no outside forces. Newton’s 2nd Law “…The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.” For example, in softball when a batter is hitting a ball, the more velocity they use from their hips and the more force and direction the batter uses from their arms, the

In the skateboard experiment, when a person was pushed with two different forces, the acceleration of the larger force allowed the person to accelerate more. A direct relationship between force and acceleration is formed. When force is applied, the acceleration also increases (assuming the mass of the person is same). This statement is supported by Newton’s second law, where the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force. The equation that is extracted from the law, Fnet = ma, proves that when constant mass is divided into a larger force (numerator), acceleration should increase. In the second part of the skateboard experiment, two people, one heavier and one lighter, were

Problem: How does the increase mass affect acceleration and the force of the accelerating object?

The objective of this lab was to determine how the acceleration of a system is related to the force applied. In order to complete this experiment we had to establish our hypothesis, independent and dependent variables and the control variables. We conducted two trials with the same masses for both trials, and changed the masses from 10 g all the way to 40 g in intervals of 5. We made sure to keep the overall weight of the system constant, since it was a control variable. We had to account for the friction of the system and developed a graph and error bars. At the end of this experiment we determined that our prediction was correct: the more force applied, the faster the acceleration.
