Physics 7:1-4 Conservation of Momentum and Energy


Reading Preparation

Text Reading: Giancoli, Physics - Principles with Applications, Chapter 7: Sections 1-4

Study Points

Key Equations

  • Definiion of force in terms of momentum: Σ   F   =   Δ p Δ t   =   m a
  • Change in momentume = Impulse Δ p   =   F t
  • Conservation of momentum in elastic collision m A v A   + m B v B   =   m A v ' A   +   m B v ' B  

Web Lecture

Read the following weblecture before chat: Momentum

Study Activity

Note: Adobe Flash is required for this simulation.

Change the masses of the balls to determine how mass changes momentum in collisions. Use the vector displays to determine the direction and relative sizes of velocity, momentum, and KE.

Physics simulation Java Applets are the product of the PHET Interactive Simulations project at the University of Colorado, Boulder.
