1 Newton’s Third Law of Motion

2 Action and Reaction Newton’s Third Law of Motion-
For every action there is an equal and opposite reaction. If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction.

3 Action and Reaction Action and Reaction Forces Don’t Cancel
Forces exerted by two objects is called action-reaction force pair Don’t cancel because they act on different objects Forces can only cancel if they act on the same object Read P

4 Momentum “quantity of motion”
A relation between a moving object and it’s mass and velocity combined Momentum = Mass X Velocity Momentum is conserved unless acted upon by an outside force! “Conservation of Momentum”
