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:
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
- Put the pole in the ground.
- Pull the string out to its maximum length.
- Walk around in a circle using the string as a guide, marking out the circle as you go.
- Start timing the person as they walk the first lap.
- Record the result.
- For Lap 2, without the person stopping, time the person jogging around the circle.
- Record the result.
- For Lap 3, without the person stopping, time the person running around the circle.
- Record the result.
- At the end of the third lap the runner stops but continue timing for another 5 seconds.
Height | Height of bounce on carpet | height of bounce on the concrete |
80 cm | 100 mm | 390 mm |
90 cm | 210 mm | 365 mm |
100 cm | 310 mm | 430 mm |
