Ground Reaction Force
Ground Reaction Force: The reaction to the force you exert on the ground and is the most important external force acting on human motion
Potentially the most damaging force affecting human motion
Such as, if you jumped off the bottom step of a staircase and locked your knees
Example:
If you drop a basketball on cement, it absorbs the force and bounces
If you drop a glass bottle, it shatters
