Energy Conversions Worksheet - Craig Fisher | Library | Formative - Free Printable

Let’s go through each question one by one. We’ll think about what each type of energy means and when it is at its maximum or present.

Question 1:
> A change from one form of energy to another is called a(n) __________.

This is the definition of an energy conversion. For example, when you turn on a light bulb, electrical energy becomes light and heat energy — that’s a conversion.

✔ Answer: conversion

Question 2:
> When the skateboarder reaches the top of the half-pipe, which type of energy is at its maximum?

At the top of the half-pipe, the skateboarder is highest above the ground. That means they have the most potential energy (specifically gravitational potential energy). They’re not moving fast there, so kinetic energy is low.

✔ Answer: c. potential energy

---

Question 3:
> As the skateboarder speeds down through the bottom of the half-pipe, which type of energy is at its maximum?

At the bottom, the skateboarder is moving fastest → that means kinetic energy is highest. Potential energy is lowest here because they’re closest to the ground.

✔ Answer: b. kinetic energy

Question 4:
> Which type of energy is present in the wound-up rubber band in a toy airplane?

A wound-up rubber band is stretched or twisted — it stores energy because of its shape. This is called elastic potential energy.

✔ Answer: d. elastic potential energy

---

Question 5:
> When the rubber band on the airplane is released, the stored energy becomes __________ energy, spinning the propeller.

When the rubber band unwinds, it makes the propeller move → that’s motion → kinetic energy.

✔ Answer: kinetic

Question 6:
> A stretched rubber band stores __________ energy.

Again, stretching something stores energy due to its position/shape → elastic potential energy. But since the blank just says “__________ energy”, and we’ve seen this before, the best fit is potential (or more specifically, elastic potential — but if only one word fits, “potential” works).

Wait — looking back at Q4, they used “elastic potential energy” as an option. Here, the sentence doesn’t specify, but in science class, we usually say a stretched rubber band stores elastic potential energy. However, sometimes worksheets accept just “potential”. Let’s check context.

In Q4, they had “elastic potential energy” as a choice. In Q6, it’s a fill-in. Since it’s a stretched rubber band, the precise term is elastic potential, but if the worksheet expects simplicity, maybe just “potential”.

But let’s be accurate: It’s elastic potential energy. However, the blank might expect just “potential” — but no, in Q4 they distinguished it. So for accuracy:

✔ Answer: elastic potential

*(Note: If your teacher accepts “potential”, that’s okay too — but technically it’s elastic potential.)*

Question 7:
> Which type of energy comes from the food you eat?

Food contains chemicals that your body breaks down to release energy → that’s chemical energy.

✔ Answer: a. chemical energy

Now let’s compile all answers clearly.

Final Answer:
1. conversion
2. c. potential energy
3. b. kinetic energy
4. d. elastic potential energy
5. kinetic
6. elastic potential
7. a. chemical energy
