Additional Details

Conceptual Physics Alive: Momentum includes a digital video and questions set with answers.

Observe Paul Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. In this video, Newton's 2nd law is rearranged to the form: Impulse = Change in Momentum. A variety of everyday examples, such as bouncing are used to support this impulse-momentum concept. Conservation of momentum is demonstrated with colliding carts on an air track.

Momentum Includes:

  • Hewitt begins with a comparison of mass and moving mass- momentum.
  • Impulse and momentum are defined.
  • Delta notation introduced.
  • Examples of impulse-momentum: Golf ball, Slingshot, Cannonballs shot from short and long cannons, Car with failed brakes, Jumping into a net, Riding with the punch when boxing, and Catching a baseball
  • Distinction between impact and impulse.
  • Bouncing and its effect on impulse. Karate and Pelton wheel
  • Demonstration of elastic collisions on an air track.
  • Demonstration of inelastic collisions on an air track.
  • Definition of a system. Pushing on automobile dashboard.
  • Momentum conservation.
  • Railroad cars example.

Next-Time Question: Demo of the swinging balls apparatus: Why will two balls not eject one ball at twice the speed? (SEE RESOURCES TAB FOR MORE)
