🏃 Part 1: Data Collection

1. Record your measurements in the data table below:

2. Which required more steps to stop completely?

Walking

Running

They were the same

🧠 Part 2: Analysis Questions

3. Explain why one speed required more steps to stop than the other. Use the terms "momentum" and "velocity" in your answer.

4. What is impulse and how does it relate to stopping?

Impulse is the force applied over time to change momentum

Impulse is how fast you can run

Impulse is the number of steps you take

Impulse is your body weight

5. Calculate: If your mass is 120 pounds and you're running at 10 feet per second, what happens to your momentum when you stop?

6. Which factors affect how quickly you can stop? (Check all that apply)

Your initial speed

The friction between your shoes and ground

Your mass

The color of your shoes

7. How does this lab relate to car safety and braking distances?

8. Extension Challenge: Design an experiment to test how different shoe types affect stopping distance.

9. Rate your understanding of momentum and impulse:

I can explain it to someone else

I understand the basic concepts

I need more practice

I'm still confused
