🏃 Part 1: Understanding Speed and Energy

1. When a ball is rolling faster, it has ________ energy.

less

the same

2. Which car would cause more damage if it hit a wall?

A car moving at 5 mph

A car moving at 30 mph

Both would cause the same damage

3. Sarah kicks two soccer balls. Ball A moves slowly and Ball B moves quickly. Which statement is true?

Ball A has more energy than Ball B

Ball B has more energy than Ball A

Both balls have the same energy

4. What happens when a fast-moving object hits something?

It transfers more energy

It transfers less energy

Speed doesn't matter

🔍 Part 2: Evidence and Reasoning

5. Tommy drops two identical rocks. Rock 1 falls from 3 feet high and Rock 2 falls from 10 feet high. Which rock will hit the ground with more energy? Use evidence to explain your answer.

6. Look at this evidence: A slow-moving bowling ball knocks down 3 pins. A fast-moving bowling ball knocks down all 10 pins. What does this tell you about speed and energy?

7. Maria notices that when she rides her bike slowly, she can stop easily. When she rides fast, it takes longer to stop. Explain why this happens using what you know about speed and energy.

🧠 Part 3: Problem Solving

8. Design a simple experiment to show that faster objects have more energy. Describe what materials you would use and what you would observe.

9. A toy car rolls down a ramp. Circle all the things that would make the car have MORE energy at the bottom:

Making the ramp steeper

Making the ramp less steep

Using a heavier car

Using a lighter car

Making the ramp longer

10. Complete this sentence: "The faster an object moves, the ________ energy it has, and the ________ effect it will have when it collides with something."

Answer: The faster an object moves, the _____________ energy it has, and the _____________ effect it will have when it collides with something.
