Friction: The Force That Slows (Part 3).
🎯 Your mission
Play with the model. Break it. Understand it.
⚡ The twist
Nature loves to surprise the careful watcher.
Mind = Blown
🔬 The more you look, the more nature shows you.
Make a hypothesis first
Before you start: write down what you think will happen, and why.
What You'll Learn
Friction is a force that opposes motion between surfaces that touch. Rough surfaces create more friction than smooth ones. Without friction, you could not walk or grip objects.
Key Words
- velocity
- momentum
Steps
Study the diagram and label the parts you recognize.
Set up a pendulum with string and a washer. Change the string length and count swings per minute for each. Graph your results.
Draw a detailed diagram of what you observe.
Write a conclusion: what did your results show? Did they match your prediction?
