Let's solve this worksheet step by step, using the definitions provided:
>
Potential Energy is stored energy and is waiting to work.
>
Kinetic Energy is energy that is working (i.e., energy of motion).
We are given a word bank:
- kinetic, potential, potential, potential, kinetic, kinetic, kinetic, potential, potential, kinetic
Now let’s go through each sentence.
---
1.
The apple in the table is ______ energy.
- The apple is at rest on the table — it has height, so it has stored gravitational potential energy.
✔ potential
2.
The apple falling from the table is ______ energy.
- The apple is moving — it has motion, so it has kinetic energy.
✔ kinetic
3.
If the rock falls from the hill, it is ______ energy.
- The rock is in motion (falling), so it's kinetic energy.
✔ kinetic
4.
If the rock is still, it is ______ energy.
- The rock is not moving, but if it's on a hill, it has stored energy due to height. So it's potential energy.
✔ potential
5.
If the cyclist is still, he has ______ energy.
- He is not moving, so no kinetic energy. But he might be at some height or just resting — in any case, if he's not moving, he has
potential energy (stored).
✔ potential
6.
If he is moving, he has ______ energy.
- Moving = motion → kinetic energy.
✔ kinetic
7.
If the yoyo is still at the top, it is ______ energy.
- At the top, it's not moving, but it has height — so potential energy.
✔ potential
8.
If the yoyo is moving, it is ______ energy.
- It’s in motion — so kinetic energy.
✔ kinetic
9.
If the boy throws the ball, it is ______ energy.
- Throwing means the ball is in motion — so kinetic energy.
✔ kinetic
10.
The ball on the boy's hand is ______ energy.
- The ball is at rest (not moving) — so it has potential energy (stored, ready to be thrown).
✔ potential

Summary Explanation:
-
Potential energy is stored energy due to position or state (e.g., height, rest).
-
Kinetic energy is energy of motion.
- When an object is
at rest, it has
potential energy.
- When an object is
moving, it has
kinetic energy.
This worksheet helps students distinguish between these two forms of mechanical energy.
