Name the main form of energy in each case.
- A boulder at the edge of a cliff.
- A moving train.
- A charged battery that is switched off.
- A drawn bow, ready to shoot.
- A whistle being blown.
Need a reminder? The key ideaShow
Potential energy , with measured from a level we choose. The change in between two heights is the same from any level, and it does not depend on the path.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. (a) Gravitational potential energy: it is high up.
Step 2. (b) Kinetic energy: it is moving.
Step 3. (c) Chemical energy, stored in the battery.
Step 4. (d) Elastic potential energy: the bow is bent.
Step 5. (e) Sound energy.
Answer: potential, kinetic, chemical, elastic potential, sound.
