Projectile Motion

from here
When a soccer ball is kicked in the air, it becomes a projectile. Its determined path is a perfect parabola, but in the soccer, wind factors comes in to play thus making the game  more difficult.

 Friction

from here

This is what causes the ball to stop moving when it is kicked on the grass.
Friction occurs because of the electromagnetic forces between charged particles of the grass and the skin of the soccer ball rubbing against each other which constitute the surfaces in contact. Friction turns kinetic energy into heat.

Drag


from here
Drag occurs when a ball kicked moving through the air. As the ball is pushing through the air, the air pushes back thus slowing it down. A way to decrease drag is by kicking the ball with a spin. Once the ball spins, the magnus affect takes place. The magnus affect decreases air resistance drastically.
