Bounce

Aim:
I want to investigate the relationship between speed, distance and time.


Hypothesis:

I think that the Harder and Higher the Ball is Dropped The Higher it will Bounce  

Equipment:

  • pole with 3.18m string attached
  • a person to move around the circle
  • stopwatch
  • paper and pen to write results

Method
  1. Put the pole in the ground.
  2. Pull the string out to its maximum length.
  3. Walk around in a circle using the string as a guide, marking out the circle as you go.
  4. Start timing the person as they walk the first lap.
  5. Record the result.
  6. For Lap 2, without the person stopping, time the person jogging around the circle.
  7. Record the result.
  8. For Lap 3, without the person stopping, time the person running around the circle.
  9. Record the result.
  10. At the end of the third lap the runner stops but continue timing for another 5 seconds.
