Soccer Kicking Physics

By Amber Holt


Kicking a soccer ball is a lot more than just putting your foot to the ball. There is a lot of physics invovled to make that happen. Newton's first law of motion that states, an object at rest will stay at rest unless acted upon by an unbalanced force, is a big part of just kicking the ball. In order for the ball to be able to go anywhere there has to be an unbalanced force and that force would be you moving your foot towards it and making contact.

Newton's second law plays a part too. The mass of the ball and the acceleration of my foot going towards the ball equals the force of the ball going into the air. When the ball is in the air, something else has to happen otherwise the ball will never come down, we call that freefall. Freefall is when the only reason an object is falling is due to gravity.

And last but certainly not least, friction affects a lot when kicking a ball too. Even when you're not literally kicking the ball there is friction. It's called static friction. That's what keeps the ball sitting on the ground. When your foot makes contact with the ball, moving it, there is kinetic friction.

In the following video you will see the guy kicking the ball. This shows all of the things I've metioned earlier.
