Which of Newton's laws of motion states, 'every action force has an equal and opposite reaction force?' A. Newton's 1st law of motion
B. Newton's 3rd law of motion
C. Newton's universal law of gravitation
D. Newton's 2nd law of motion

Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object
