Study Notes
Friction
- Friction is a force that opposes motion between surfaces in contact.
- The rougher the surface, the greater the friction.
- Friction produces heat.
- If you rub your hands together, they will get warmer.
- Friction is directly proportional to the normal force
- The formula for frictional force (Ff) is Ff = µFn, where µ is the coefficient of friction and Fn is the normal force.
- The coefficient of friction (µ) depends on the nature of the surfaces in contact.
- A higher coefficient of friction means greater friction.
Visual Examples
- Images illustrate various examples of friction, including pushing a refrigerator, cyclists experiencing air resistance, and more.
