Answers
Answer:
The third law of motion states that for every action, there is an equal and opposite reaction. This can be observed both in objects at rest and those that are accelerating. For example, a resting box pushes down on the ground due to a gravitational force. ... These forces balance so no acceleration of the box occurs.

Answer:
THIRD LAW OF MOTION
STATEMENT:
To every action there is always an equal reaction.
DESCRIPTION:
Let body A exert a force on another body B, the body reacts against this force and exerts a force on body A.The force exerted by body A on B is action force whereas the force exerted by body B on A is reaction force.
EXAMPLES:
Helicopters similarly create lift by pushing air down, thereby experiencing an upward reaction force. Birds and airplanes also fly by exerting force on air in a direction opposite to that of whatever force they need. For example, the wings of a bird force air downward and backward in order to get lift and forward motion.Other examples of Newton’s third law are easy to find. As a professor paces in front of a whiteboard, she exerts a force backward on the floor. The floor exerts a reaction force forward on the professor that causes her to accelerate forward.

You can see evidence of the wheels pushing backward when tires spin on a gravel road and throw rocks backward.
