Soccer, the most popular game in the world, has a lot of physics under the surface.

The first is Newtons first law. The law of inertia. The ball stays at rest until acted upon. usually by a players foot. Then it stops only by an outside force. This could be friction from the field, air resistance, or another player. You can also factor in Newton's other two laws as well as momentum and a variety of others.

The best physics in my opinion however, is the bending of the ball on a shot, or the Magnus affect. The bend and dip on the ball is mostly because the player kicks the ball at a certain angle and velocity. The players put spin on the ball in order to neglect air resistance. On average, a shot is kicked at around 65 mph, after about 10 meters, the speed drops dramatically, and the drag on the ball will dramatically increase. As the velocity drops, the Magnus effect substantially increases and this is the major reason why the ball will dip and curve through the air.
