Let's solve this step by step based on the images provided in the "Forms of Energy" worksheet.
We are asked to identify the
correct form of energy for each image. Here are the images and their corresponding energy forms:
---
1. Torch with a flame
-
Image: A lit torch producing fire.
-
Energy Type: The flame produces
heat and
light.
-
✔ Answer: Thermal Energy (or Heat Energy)
> 🔥 *Explanation:* The burning fuel in the torch releases heat and light, but the primary form here is thermal energy.
---
2. Light bulb
-
Image: A glowing light bulb.
-
Energy Type: It emits
light.
-
✔ Answer: Light Energy
> 💡 *Explanation:* An electric current passes through the filament, producing visible light.
---
3. Boombox (radio/music player)
-
Image: A stereo system with speakers.
-
Energy Type: It produces
sound.
-
✔ Answer: Sound Energy
> 🎧 *Explanation:* The device converts electrical energy into sound waves.
---
4. Marble rolling down a track
-
Image: A marble on a track, possibly at the top of a slope or moving.
-
Energy Type: This shows motion and position — it involves
potential and kinetic energy, but the main idea is
mechanical energy.
-
✔ Answer: Mechanical Energy
> ⚙️ *Explanation:* Mechanical energy includes both potential (stored due to height) and kinetic (energy of motion). The marble has mechanical energy as it moves.
---
5. Sun
-
Image: A smiling sun.
-
Energy Type: The sun emits
light and heat.
-
✔ Answer: Radiant Energy (or Solar Energy)
> ☀️ *Explanation:* The sun radiates energy in the form of electromagnetic waves (light and heat), which we call radiant energy.
---
6. Volcano erupting
-
Image: A volcano spewing lava and ash.
-
Energy Type: Internal heat causes eruptions — this is
thermal energy from within the Earth.
-
✔ Answer: Thermal Energy (or Geothermal Energy)
> 🌋 *Explanation:* The molten rock (magma) contains intense heat, so this is thermal energy stored in the Earth’s core.
---
7. Three colored beams (red, yellow, green)
-
Image: Colored rays coming from sources.
-
Energy Type: These represent
light traveling in different colors.
-
✔ Answer: Radiant Energy
> 🌈 *Explanation:* Light is a form of radiant energy that travels in waves.
---
8. Guitar
-
Image: A guitar.
-
Energy Type: When played, it vibrates and produces
sound.
-
✔ Answer: Sound Energy
> 🎸 *Explanation:* The strings vibrate when plucked, creating sound waves.
---
✔ Final Answers:
| Image | Form of Energy |
|------|----------------|
| 1. Torch |
