$<font color="green"><i>$

• Newton's Second Law of Motion describes relation between a cause (external force) and an effect (acceleration).

• When a human body accelerates, we know that a non-zero resultant external force must be acting on it.

• If a non-zero resultant external force ΣF (the sum of all external forces acting on the body) acts on a human body with the mass m, we know that the body must accelerate.

• This fact can be mathematically expressed as:

ΣF=ma

where a is acceleration.

Every time a human body, or any object in sport, decreases its velocity, increases its velocity, or changes the direction of its motion, it moves with non-zero acceleration. Resultant external force is the cause of this acceleration.
