Unit 2 Force & Motion Newton’s 3rd Law

Have You Ever Heard The Phrase… Your actions have consequences? Newton’s 3rd Law is similar to this idea

Newton’s 3rd Law Newton’s Third Law of Motion - forces always act in equal but opposite pairs (for every action there is an equal & opposite reaction)

Action-Reaction Forces action-reaction forces - equal & opposite, but do not cancel because they act on different objects (forces can only cancel if they act on the same object) such forces can be difficult to identify… b/c one of the objects is so massive that it appears to remain motionless even when a force acts on it (more mass = more inertia = barely moves)
