Speed & energy of collisions — Homework
Use what you learned about speed and collisions to answer.
- 1.A ball rolled hard into a cup and a ball rolled gently into the same cup. Which carries more energy of motion?
- 2.Why does a faster-moving object usually cause a bigger effect in a collision?
- 3.Two identical bikes crash into a soft barrier, one going fast and one going slow. Which crash likely dents the barrier more, and why?
- 4.Describe a real or imagined collision and explain what the result tells you about the energy involved.
- 5.If you want to test whether speed really changes collision energy, what is the one thing you must keep the same between trials?
