In soccer there are several forces acting on a soccer ball
If there was no gravity, the soccer ball would fly through the air and never come back. Tahoe players also stay on ground because of gravity. Altered gravity vacancy change how high or how low the ball goes
Something that will affect the way the soccer ball moves is velocity. Without knowing velocity of the soccer ball, you will not be able to get it. Also you have to know velocity of it when you kick it, so you can accurately pass to a teammate. Knowing the direction of the soccer ball is very important in the game of soccer.
