Physics in Soccer Free Kicks by caroline jennings

In soccer the friction is the grass because it helps gravity slow the ball down, so in free kicks if you want to play it on the ground, you have to kick the ball harder. This is shown in the free body diagram. When taking a free kick the kicker has to know how short, long, fast or slow he/she wants the ball to go.

The physics of free kicks - How It Works

With Ronaldo’s knuckleball free kicks, he aims to kick the ball with as little spin as possible. As it flies through the air, a layer of air wraps itself tightly round the ball. If that layer is disrupted by an imperfection, like a stitched panel edge, it will deviate, causing that unexpected swerve and dip.

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.
