  1. Momentum • Inertia • Impulse • Newton’s Second Law • Importance of follow through • Applications Momentum and Impulse

  2. Momentum • A team is said to have Momentum if they are “on a roll,” or “hard to stop.”

  4. Momentum • _________ • Any moving body has momentum

  5. Momentum • An object’s momentum depends on its mass and how fast it is moving. A truck traveling 5 km/h has more momentum than a Smart car at the same speed because it is harder to stop.

  9. Check Your Understanding • Determine the momentum of a Pacific leatherback turtle of mass 8.6 x 102 kg, swimming at a velocity of 1.3 m/s [forward]

  10. Check Your Understanding A car possesses …………. • its velocity was doubled. • its mass was …………… • its ………….

  12. Will it break?

  13. From Newton’s Second Law

  14. ________ • Its direction is the same as the change in momentum

  15. Impulse • Impulse = FnetΔt • _______ • If you increase Δt, Fnet will decrease • If you are trying to catch a ball and you move your hands back with the ball as it approaches, you will increase the time needed to stop the momentum and thus, decrease the F required  hurts less!
