... • Newton’s Laws of Motion are: (1) Acceleration (or deceleration) occurs if and only if there is a net external force. (2) a = F/m [Note this is a vector eqn.] (3) The force exerted by a first object on a second is always equal and opposite the the force exerted by the second on the first. F12 = ...

... What is Newton’s Third Law of Motion? • Newton’s third law states: Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. • In other words, all forces act in pairs. • Action and reaction forces are present even when there is no motio ...
