Transcript

  • 1. Conservation ofEnergy andMomentum inCollisionsSection 7.4 – 7.5
  • 2. • How do we apply conservation of energy and momentum to one dimensional problems?Conservation ofMomentum
  • 3. • Momentum is conserved in all collisions• Elastic Collisions: collisions where kinetic energy is conserved• Inelastic Collisions:Conservation
  • 4. • Two objects colliding elastically• Know masses and initial speedsElastic Collisions in OneDimension
  • 5. • Momentum and kinetic energy are conserved• mAvA + mBvB = mAvA’ + mBvB’• Use ‘ to show final speeds• Two unknowns!Elastic Collisions in OneDimension
  • 6. • Do some algebra (page 176, if you are interested)• vA – vB = vA’ – vB’Elastic Collisions
  • 7. • A proton of mass 1.01 u traveling with a speed of 3.60 x 104 m/s has an elastic head-on collision with a helium nucleus. The helium nucleus has a mass of 4.00 u and is initially at rest. What are the velocities of the proton and helium nucleus after the collision?• 1 u = 1 unified atomic mass unit = 3.6 x 10-27 kg, but we don’t need thisExample
  • 8. • Read Sections 7.4 and 7.5• Do Problems # 22 - 27, Page 189Homework
