Collisions Definition Two objects meet in opposite direction Momentum is conserved Elastic collision Definition Two objects collide and bounces back m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2 Kinetic energy is conserved Inelastic collision

  1. Collisions

  2. Definition

  3. Two objects meet in opposite direction

  4. Momentum is conserved

  5. Elastic collision

  6. Definition

  7. Two objects collide and bounces back

  9. m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2

  10. Kinetic energy is conserved

  11. Inelastic collision

  12. Definition

  13. Two objects collide and stick together

  15. m 1 u 1 + m 2 u 2 = v ( m 1 + m 2 )

  16. Kinetic energy is not conserved
