Types of Collisions

• Elastic

  • KE is conserved: no sound or heat produced
  • sub atomic particles, repelling magnets, a “perfect” super ball

• Inelastic (partially elastic)

  • some KE is lost as heat or sound
  • Is a broad range containing most collisions

• Completely Inelastic

  • more KE is lost as heat or sound
  • the colliding objects stick together
