This worksheet helps students visualize the difference between stored potential energy and active kinetic energy through simple, relatable examples.

I'll solve this worksheet on Potential vs. Kinetic Energy by analyzing each scenario and determining which type of energy is present.

Let me start by understanding the definitions provided:
- Potential Energy: stored energy and is waiting to work
- Kinetic Energy: energy that is working

Now I'll go through each example:

1. The apple in the tree: This is potential energy because the apple has stored energy due to its height (gravitational potential energy) and is waiting to fall.

2. The apple falling from the tree: This is kinetic energy because the apple is in motion as it falls.

3. If the rubber band is still: This is potential energy because a stationary rubber band has stored elastic potential energy.

4. If the rubber band is stretched: This is still potential energy because even when stretched, it's storing elastic potential energy, waiting to be released.

5. If the roller coaster is still: This is potential energy (specifically gravitational potential energy if it's at the top of a hill).

6. If it is moving: This is kinetic energy because the roller coaster is in motion.

7. If the yoyo is still at the top: This is potential energy (gravitational potential energy).

8. If the yoyo is moving: This is kinetic energy because it's in motion.

9. If the bow string is still: This is potential energy (elastic potential energy).

10. If the bow string is pulled: This is still potential energy (elastic potential energy) because it's storing energy that will be released when let go.

Wait, let me reconsider #4 and #10. When a rubber band is stretched or a bow string is pulled, they are storing potential energy, not yet converting it to kinetic energy. The energy becomes kinetic only when they snap back or release.

The completed worksheet should read:

The apple in the tree is potential energy.
The apple falling from the tree is kinetic energy.
If the rubber band is still it is potential energy.
If the rubber band is stretched it is potential energy.
If the roller coaster is still, it is potential energy.
If it is moving, it is kinetic energy.
If the yoyo is still at the top, it is potential energy.
If the yoyo is moving, it is kinetic energy.
If the bow string is still it is potential energy.
If the bow string is pulled it is potential energy.

This makes sense because potential energy is stored energy waiting to be used, while kinetic energy is energy of motion. Even when stretched or pulled, objects are storing potential energy rather than actively using kinetic energy.
