kick a soccer ball? When you kick a soccer ball, multiple things happen. First of all, your leg is putting kinetic (or “movement”) energy into the ball. The formula for this is: Here the kinetic energy equals one half of the mass of your leg multi-plied by the velocity of your leg, as it hits the ball, squared. Another thing
The Physics behind Soccer Kicks. Soccer is a sport that requires speed, strength, endurance and strategy, but it seems that good ball control in soccer also requires a good grasp of physics. In this article, I will present a few basic laws in physics and show how these laws are reflected in soccer. Some of the facts may seem a bit trivial, but no one said physics lacks logic.

The Physics Of Soccer – The Magnus Effect. When a soccer player kicks a ball off-center it causes the ball to spin. The direction and speed of the spin will determine how much the ball curves during flight. It's the same principle as a curve ball in baseball.
The flight of a soccer ball is a fairly complex physics problem. The flight path is described by integrating Netwon's second law of motion. The external forces on the ball are the weight , the aerodynamic side force , and the aerodynamic drag .

Friction. Whenever the soccer ball is kicked on the ground there is always a force parallel, but opposite of the soccer ball according to soccer physics. This parallel and opposite force is called friction. Friction is caused when two opposing surfaces make contact with each other.
When a soccer player’s kick creates a counter-clockwise spin, the Magnus force acts left on the ball, causing the ball to curve left — and vice-versa.
Friction is in soccer. Friction 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. It can be undesirable because it can prevent the ball from going into the goal. Gravity is another force that affects soccer. If there was no gravity, the soccer ball would fly through the air and never come back.
