In soccer there is physcis. After running full speed trying to chase down a ball, one might find it hard to stop. This is because of Newton's First law, an object in motion stays in motion unless acted upon by an outside force. This is why we can't stop immediatly after running. There is also physics when you kick the ball. Newton's third law states that for every action there is an equal and opposite reaction. The action in this case is you kicking the ball and even though it's hardly noticable, the ball exerts a force on your foot that is equal to the force you are striking the ball with.
