THE FORCES CREATED IN SPORTS

Force is defined as the cause that causes any change in the motion or geometry of bodies.
A body can simultaneously receive many forces, the sum of which will be at each point a constitutive force and a constitutive moment.
When these forces neutralize each other then the body is said to be in a state of equilibrium.

As far as free bodies are concerned, the force is generally the cause of change in their kinetic state, i.e. the one that accelerates or decelerates them.

What is mentioned there is a lesson in the literature as biomechanics of the movements made by the human body.
