Meaning
Friction is a force that slows things down when two surfaces are touching each other.
About Friction
- Friction can only happen when two surfaces are touching so it is called a "Contact Force".
- Friction depends on the texture of a surface.
- The rougher a surface is, the more friction an object will experience when it is moving.
- The smoother a surface is, the less friction an object will experience.
- A surface could be described as high friction or low friction.
