Step-by-step solution for: Forms of Energy Worksheet | Teach Starter
Let’s go step by step to match each form of energy with its correct definition, and then identify the forms of energy in each scenario.
---
Part 1: Match the form of energy with its definition
We have 5 types of energy on the left (numbered 1–5) and 5 definitions on the right (labeled a–e). Let’s think about what each one means:
1. Mechanical energy – This is energy from motion or position. Like when something moves or is lifted up. That matches c. energy of motion.
2. Electrical energy – This comes from moving electrons, like in wires or batteries. So that’s e. energy of flowing electrons.
3. Light energy – You can see it! It’s what lets you see things. So that’s a. energy that is detected with your eyes.
4. Thermal energy – This is heat energy. When something feels hot, it has thermal energy. So that’s b. energy that comes from heat.
5. Sound energy – Sound happens when things vibrate — like guitar strings or speakers. So that’s d. energy caused by the vibration of matter.
✔ So the matches are:
1 → c
2 → e
3 → a
4 → b
5 → d

Part 2: Write the form(s) of energy present in each scenario
Now let’s look at each situation and think about what kind(s) of energy are involved.
6. Boiling water on a stove top
→ The stove gives off heat (thermal) energy to boil the water.
→ Also, if the water is bubbling or moving, there’s some mechanical energy too. But mainly thermal.
👉 Answer: Thermal energy (and maybe mechanical)
7. Using a flashlight
→ Flashlights use batteries → that’s electrical energy.
→ They produce light → so also light energy.
👉 Answer: Electrical and light energy
8. Blowing a whistle
→ You blow air → that’s movement → mechanical energy.
→ The whistle makes sound → sound energy.
👉 Answer: Mechanical and sound energy
9. Driving a car
→ Car engine uses fuel or electricity → involves chemical or electrical energy (but since we’re matching from our list, focus on what’s visible/obvious).
→ Car moves → mechanical energy.
→ Engine gets hot → thermal energy.
→ Maybe even sound from the engine → sound energy.
But for simplicity, main ones: mechanical and thermal.
👉 Answer: Mechanical and thermal energy
10. Turning on a ceiling fan
→ Fan uses electricity → electrical energy.
→ Blades spin → mechanical energy.
→ Might make a little noise → sound energy (optional).
Main ones: electrical and mechanical.
👉 Answer: Electrical and mechanical energy
11. Playing a guitar
→ You strum strings → they vibrate → sound energy.
→ Your hand moves → mechanical energy.
👉 Answer: Mechanical and sound energy

Final Answer:
Matching:
1. mechanical energy → c. energy of motion
2. electrical energy → e. energy of flowing electrons
3. light energy → a. energy that is detected with your eyes
4. thermal energy → b. energy that comes from heat
5. sound energy → d. energy caused by the vibration of matter
Scenarios:
6. boiling water on a stove top → thermal energy
7. using a flashlight → electrical and light energy
8. blowing a whistle → mechanical and sound energy
9. driving a car → mechanical and thermal energy
10. turning on a ceiling fan → electrical and mechanical energy
11. playing a guitar → mechanical and sound energy
