Final answer:

Newton's second law of motion relates force, mass, and acceleration, and athletes use sand or cushion in high jumping for safety and impact absorption.


Explanation:

Newton's second law of motion states that force equals mass times acceleration. Mathematically, it is expressed as Fnet = ma or EF = ma. This law explains how force causes changes in motion by showing the relationship between force, mass, and acceleration.

In high jumping, an athlete puts sand or cushion on the ground to provide a safe landing surface due to the athlete's motion involving rapid changes in speed and direction. The use of sand or cushion helps absorb impact forces and reduce the risk of injury during the high jump.
