Which of the following is Newton's 3rd Law of Motion?

• An object at rest will stay at rest, and an object in motion will stay in motion unless an unbalanced force acts upon it.

• Force is equal to the mass of an object times its acceleration.

• For every force acting on an object, that object exerts an equal force in the opposite direction on the first object. 

• There is no such thing as Newton's Laws of Motion.
