1. NEWTON’S LAWS

2. Newton’s First Law

3. An example Also called “Newton’s Law of Inertia”

4. Inertia An object’s tendency to resist a change in motion

5. Newton’s Second Law F = m x a

6. Newton’s Second Law Part 1: Acceleration depends on mass Part 2: Acceleration depends on force

7. Example: Mr. Parzych Bowling How much force is need for a bowling ball with a mass of 5 kg to be accelerated at a rate of 2 m/s/s?

8. Example: Mr. Parzych Bowling F = m x a F= (5 kg) * ( 2 m/s/s) F= 10 N a= 2 m/s/s m= 5 kg

10. Action and Reaction Forces

11. Examples of Force Pairs

12. Volleyball Spike

13. Hunting

14. Golf

15. Pushing Against A Wall

16. Balloon Rocket

17. Effects of Reaction Forces Hard to see the effect of the ball pulling on the earth. The earth is extremely massive, so it’s acceleration will be infintessimally small F= m x a

18. Momentum Momentum is the combined mass and velocity of an object.

19. Transfer of Momentum

20. Conservation of Momentum
