Carts and Wheels
Explore Circles, Rotation, and Revolution
Discover how wheels work and learn about circles, rotation, and revolution! Try different wheel sizes to see how they affect movement.
How to Use This Demo
- Select a wheel size from the options above
- Click "Move Cart" to see the wheels rotate and the cart move
- Observe how different wheel sizes affect movement
- Learn about circle properties (radius, diameter, circumference)
- Reset the cart anytime with the "Reset" button
- Notice the relationship between wheel size and distance traveled
Observation:
Wheels make it easier to move heavy objects. The size of the wheel affects how far the cart moves with each rotation!
The Science Behind Wheels
Key Concepts:
Rotation is when an object spins around its own axis. Revolution is when an object moves around another object in a circular path.
| Circle Property | Definition | Relationship |
|---|---|---|
| Radius | Distance from center to edge | Half of diameter |
| Diameter | Distance across circle through center | Twice the radius |
| Circumference | Distance around the circle | π × diameter |
Real-World Applications:
Wheels are used in many machines and vehicles to reduce friction and make movement easier. The invention of the wheel was one of the most important discoveries in human history!
