- Multiple ChoicePlease save your changes before editing any questions.What is the 3rd Law of Motion?A body at rest will stay at rest, and a body in motion will stay in motion unless acted upon by an external force.The force acting on an object is equal to the mass of that object times its acceleration.The principle that 2 particles attract each other with forces directly proportional to the product of their masses divided by the square root of the distance between them.For every action, there is an equal and opposite reaction.
