Here’s the solution to the worksheet, with explanations for each answer:
---
1. When a dog is sleeping, it is _potential_ energy.
✔ Explanation: Potential energy is stored energy due to position or state. A sleeping dog is at rest — not moving — so it has potential energy (it could wake up and move, but isn’t currently). It’s not actively doing work or in motion.
---
2. When a dog is running, it is _kinetic_ energy.
✔ Explanation: Kinetic energy is the energy of motion. Since the dog is running (moving), it has kinetic energy.
---
3. If the light is on, it is _kinetic_ energy.
✔ Explanation: When a light is on, energy is being actively converted — electrical energy becomes light and heat energy. This active flow and transformation of energy is considered kinetic energy (energy in motion/transfer).
---
4. If the light is off, it is _potential_ energy.
✔ Explanation: When the light is off, no energy is being used or transferred — but the potential to turn it on still exists (e.g., electricity is available in the circuit). So, we consider this stored or dormant energy as potential energy.
---
5. When the orange is in the tree, it is _potential_ energy.
✔ Explanation: The orange has gravitational potential energy because of its height above the ground. It’s not moving yet, but if it falls, that stored energy will convert into motion (kinetic energy).
---
6. When the orange is falling from the tree, it is _kinetic_ energy.
✔ Explanation: As the orange falls, it is moving under gravity — so it now has kinetic energy. Its potential energy is decreasing as it falls, and kinetic energy is increasing.
---
✔ Final Answers:
1.
potential
2.
kinetic
3.
kinetic
4.
potential
5.
potential
6.
kinetic

📌
Key Concept Reminder:
-
Kinetic Energy = energy of motion (things moving)
-
Potential Energy = stored energy (ready to be used, often due to position or state)
This worksheet helps students understand how energy changes form based on an object’s state or movement!
Parent Tip: Review the logic above to help your child master the concept of kinetic energy worksheet answers.
