04-16-08 - Conservation Of Momentum

  1. 1. Conservation of Momentum
  2. 2. Types of Collisions Elastic Two objects collide and bounce off each other Inelastic Two objects collide and stick together Explosion One object separates into two fragments
  3. 3. The momentum of any closed, isolated system does not change. The momentum before an event, p i , is equal to the momentum after the event, p f . p i = p f m 1 v i + m 2 v i = m 1 v f + m 2 v f where v i is the velocity before the event and v f is the velocity after
  4. 4. Examine elastic and inelastic collisions in one and two dimensions at these simulation sites: Link1 and link2 Computer Simulations
