Answer using your marble collision lab data and reasoning.
- 1.You release a marble from 10 cm and it pushes a cup 4 cm. You release it from 20 cm and it pushes the cup 9 cm. Which height transferred more energy?
- 2.Why must the marble, ramp, and target stay the same in every trial of this investigation?
- 3.Why do scientists repeat a trial instead of trusting a single result?
- 4.Describe the pattern you would expect between release height and push distance, and explain why that pattern makes sense.
