7. Which law describes when a person lands on a trampoline and bounces upward again? Also,
EXPLAIN WHY.

Newton's Third Law

Explanation:

Newton's third law

Newton's third law: “for every action, there is an equal and opposite reaction.” This is where you get the bounce. When you push down on the trampoline (or fall downward onto the trampoline bed), Newton's third law says that an equal and opposite reaction pushes back.

:)

It is Newton's 3rd law

Explanation:

Because: For every action force: (person jumping on a trampoline) there is a equal yet opposite reaction. Reaction force: (The trampoline pushed up against the person's feet.)
