Final answer:
Force and leverage explain how the body moves.
Step-by-step explanation:
Force and leverage are the two concepts that explain how the body moves.
Force is a push or pull that can cause an object to move or change its velocity. In the human body, muscles generate force to produce movement.
Leverage refers to the mechanical advantage obtained by using a lever. For example, bones in the body act as levers, allowing muscles to produce movement efficiently.
