15 3 Forms Of Energy Worksheets - Free PDF at worksheeto.com - Free Printable

Here's the completed worksheet with explanations for each answer.

---

Part 1: Put names of object for each source of energy below.

| Energy Source | Names of Object (Examples) |
|-------------------|----------------------------------------------|
| Sound | Drum, Bell, Speaker, Whistle |
| Mechanical | Windmill, Car, Bicycle, Pendulum Clock |
| Heat and Light | Sun, Campfire, Light Bulb, Candle |
| Chemical | Battery, Food, Gasoline, Wood |
| Electrical | Flashlight, TV, Computer, Power Outlet |
| Nuclear | Nuclear Power Plant, Atomic Bomb, Reactor |

> Explanation:
> - Sound comes from vibrating objects like drums or speakers.
> - Mechanical energy is motion or position energy — windmills and cars are classic examples.
> - Heat and Light often come together from sources like the sun or fire.
> - Chemical energy is stored in bonds — batteries and food release it when used.
> - Electrical energy powers devices like flashlights or computers.
> - Nuclear energy comes from reactions in atomic nuclei — power plants or bombs.

Part 2: For each picture write what the source of energy is.

*(Top Row, Left to Right)*

1. Torch / Flame → Heat and Light
*Explanation*: A torch produces both heat and visible light through combustion.

2. Flashlight → Electrical
*Explanation*: It runs on batteries, which provide electrical energy to power the bulb.

3. Race Car → Chemical
*Explanation*: The car’s engine burns fuel (gasoline), which is a chemical energy source.

*(Bottom Row, Left to Right)*

4. Windmill → Mechanical
*Explanation*: The wind turns the blades — this motion is mechanical energy.

5. Campfire → Heat and Light
*Explanation*: Burning wood releases heat and light energy.

6. Baseball Player Swinging Bat → Mechanical
*Explanation*: The player’s muscles convert chemical energy into kinetic (mechanical) energy to swing the bat.
