Let's solve this step by step based on the definitions provided:
-
Potential Energy: Stored energy, waiting to work (e.g., due to position or state).
-
Kinetic Energy: Energy of motion — it’s working.
Now, let’s go through each sentence and determine whether it describes
potential or
kinetic energy.

1.
The apple in the table is __________ energy.
→ The apple is at rest on the table, so it has stored energy due to its height above the ground.
✔ Potential Energy
2.
The apple falling from the table is __________ energy.
→ The apple is in motion, so it’s actively moving.
✔ Kinetic Energy
3.
If the rock falls from the hill, it is __________ energy.
→ Falling means it's in motion.
✔ Kinetic Energy
4.
If the rock is still, it is __________ energy.
→ It’s at rest but at a height, so it has stored gravitational potential energy.
✔ Potential Energy
5.
If the cyclist is still, he has __________ energy.
→ He’s not moving, so no motion energy. But he might be at a height or just resting — still, no kinetic energy.
✔ Potential Energy *(Note: This could be ambiguous, but since he's not moving, we assume it's potential energy due to position or stored energy)*
6.
If he is moving, he has __________ energy.
→ Motion = kinetic energy.
✔ Kinetic Energy
7.
If the yoyo is still at the top, it is __________ energy.
→ At the top, it’s momentarily stopped but has height → stored energy.
✔ Potential Energy
8.
If the yoyo is moving, it is __________ energy.
→ Moving down or up → in motion.
✔ Kinetic Energy
9.
If the boy throws the ball is __________ energy.
→ "Throws" implies motion — the ball is being thrown, so it’s moving.
✔ Kinetic Energy
10.
The ball on the boy's hand is __________ energy.
→ Ball is at rest in his hand, not moving.
✔ Potential Energy

✔ Final Answers:
1. The apple in the table is
potential energy.
2. The apple falling from the table is
kinetic energy.
3. If the rock falls from the hill, it is
kinetic energy.
4. If the rock is still, it is
potential energy.
5. If the cyclist is still, he has
potential energy.
6. If he is moving, he has
kinetic energy.
7. If the yoyo is still at the top, it is
potential energy.
8. If the yoyo is moving, it is
kinetic energy.
9. If the boy throws the ball is
kinetic energy.
10. The ball on the boy's hand is
potential energy.

🌟 Explanation Summary:
-
Potential Energy = stored, at rest, ready to move (due to height, position, or stretch).
-
Kinetic Energy = energy of motion — something is actually moving.
This worksheet helps students understand how energy transforms between potential and kinetic forms depending on motion and position.
Parent Tip: Review the logic above to help your child master the concept of energy worksheet middle school.
