Friction
1. Prevents your soccer ball from going forward forever when it is kicked. The soccer ball rubs against the ground, which causes resistance and slows the ball down this can cause the ball from not going into the goal. 2. Sliding friction pushes against an object when that object that is moving but not leaving the ground. 3. The higher the air pressure, the higher the air resistance. After a soccer ball is kicked if you head the ball the pressure of the air in front of the ball increases, causing air resistance to rise. The change in air resistance causes the soccer ball to slow down. 4. To complete a perfect header, it depends on the motion of your head, the motion of the ball, and how the ball bounces off your head.
Forces
1. Gravity is another force that affects soccer. If there was no gravity, the soccer ball would fly through the air and never come back. The players stay grounded too because of gravity. A change in gravity can change how high or how low the ball goes. 2. The curling of a soccer ball is caused by kicking if slightly off center which …show more content…

Momentum affects how far the soccer ball goes. The more momentum you have when you kick the soccer ball the faster it will travel. 2. When a soccer ball is received by a player, they use thier feet to slow down the momentum of the ball. This allow more control over the ball.. 3. Newon’s law states that “any object at rest, will tend to stay at rest, and any object in motion, will tend to stay in motion unless acted on by an unbalanced force.” a. Unbalance force could be gravity, wind or any moving object b. In soccer the unbalanced force is usually a player’s foot c. Players use muscles in the body to create a force to move their leg and kick the ball. d. When the ball is at rest, it will stay at rest but once kicked, it will keep moving in a straight line without any intent of stopping because of the physics of soccer. e. The ball stops eventually because of friction and Earth’s gravitational
