Bouncing Ball

Recap: Describe the motion of the bouncing ball
Recap: Sketch s-t, v-t and a-t graphs

  • Describe the conversion of energies during the motion from point of release to just before hitting the surface 
  • Explain why the returned height after each bounce is less

Task: To investigate the height of bounce
  • Investigate whether the reduction in returned height is due to the following two possible theory or due to other relations?
    • constant ratio of height reach after bounce to max height before bounce
    • constant ratio of velocity immediately after bounce to velocity immediately before bounce
  • What could be the mathematical difference between the two theories?
Knowledge to complete activity
  • Conservation of energy
  • Kinetic and potential energy
