Answer:
Action and reaction forces.
Explanation:
For every action, there is a reaction and it is equal and opposite. If object A exerts a force on object B, then object B will exert a force with the same power back.
Newton's third law of motion is that "Every action has an equal and opposite reaction."
For example, when a rocket is launched, the boosters apply force on the ground and the ground pushes back, which makes the rocket take off.
