Step-by-step solution for: Forms Of Energy Worksheet: Fill In The Blanks | MomJunction
Sure! Let’s solve the fill-in-the-blank worksheet titled “Different Types of Energy” using the words from the word bank.
---
> Electrical, power plants, light, chemical, work, electrical, mechanical, nuclear, form, kinetic, destroyed, thermal, radiate, kinetic
*(Note: “electrical” and “kinetic” appear twice — probably a formatting error, but we’ll use them as needed.)*
---
## ✔ Solved Answers with Explanations:
---
1. Energy is the ability to do _work_.
🔹 Explanation: In physics, energy is defined as the capacity to do work. Work is force applied over a distance — so energy enables physical change or motion.
---
2. Energy can neither be created nor _destroyed_.
🔹 Explanation: This is the Law of Conservation of Energy — energy cannot be created or destroyed, only transformed or transferred from one form to another.
---
3. Energy can be transferred from one _form_ to the other.
🔹 Explanation: Energy changes forms — for example, chemical energy in food becomes kinetic energy when you move, or electrical energy becomes light and thermal energy in a bulb.
---
4. The energy that is caused due to the energy stored in objects by tension is known as _mechanical_ energy.
🔹 Explanation: Objects under tension (like a stretched rubber band or compressed spring) store elastic potential energy, which is a type of mechanical energy (energy associated with motion or position).
> *Note: Some might argue “elastic” is more precise, but since it’s not in the word bank, “mechanical” is the best fit here.*
---
5. The energy that comes from the heat of a fire is known as _thermal_ energy.
🔹 Explanation: Thermal energy is the internal energy of a system due to the motion of its particles — heat from fire is a classic example.
---
6. Any substance that can be used as a fuel contains _chemical_ energy.
🔹 Explanation: Fuels (like gasoline, wood, coal) store energy in their chemical bonds. When burned, this chemical energy is released as heat and light.
---
7. The sun provides the earth with _light_ energy.
🔹 Explanation: The Sun emits electromagnetic radiation, including visible light, which reaches Earth and supports life through photosynthesis and warmth.
> *Note: “radiant” is also correct (sun emits radiant energy), and it’s in the word bank — but “light” is more specific and commonly used at this level. If “radiant” was intended, it could also fit. However, “light” is listed and appropriate.*
---
8. Radiant energy is produced by the movement of _electrical_ charges.
🔹 Explanation: Radiant energy (like light, radio waves, X-rays) is electromagnetic radiation, which is produced by accelerating electrical charges. For example, electrons moving in an antenna produce radio waves.
> *Note: “electrical” is in the word bank and fits here. While “electrons” would be more precise, “electrical” is the best available term.*

## 🧾 Final Completed Worksheet:
1. Energy is the ability to do work.
2. Energy can neither be created nor destroyed.
3. Energy can be transferred from one form to the other.
4. The energy that is caused due to the energy stored in objects by tension is known as mechanical energy.
5. The energy that comes from the heat of a fire is known as thermal energy.
6. Any substance that can be used as a fuel contains chemical energy.

8. Radiant energy is produced by the movement of electrical charges.
