  7. Topics: Center of Mass Newton’s Laws Mechanical Energy

  8. Center of Mass Properties • Mass “acts” at CM • CM stable at lowest point • Center of Mass Demos • CM location • CM motion

  9. Center of Percussion • “Dynamic” CM • Baseball bat example • Tennis racket

  10. Kinematics and Dynamics

  11. Newton’s Laws of Motion

  12. Newton’s First Lawa. An object at rest tends to remain at rest.b. An object in motion tends to remain in motion in a straight line with a constant speed.

  13. Newton’s First Law a. An object at rest tends to remain at rest.

  14. Newton’s First Lawb. An object in motion tends to remain in motion in a straight line with a constant speed.

  15. Test Question:Masses hanging in series

  16. Forces and Impulse

  17. Funnel Cart

  18. LeaningTowerofPisa

  19. Newton’s Second LawF = m a or a = F/mwhere F is the force,m is the mass, anda is the acceleration
