Newton's Third Law Worksheets

What does Newton´s 3rd Law of motion say?

• An object at rest will stay at rest, and an object in motion will stay in motion at constant velocity, unless acted upon by an unbalanced force.

• For every action there is an equal and opposite reaction

• Force equals Mass times acceleration
