What does Newton's Third Law of Motion state?

For every action, there is an equal and opposite reaction.

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Energy cannot be created or destroyed.
