3. Friction (Right) What is friction? What three factors affect friction?
How does friction work?
The resistance that one surface or object encounters when moving over another.
-The types of surfaces in contact
- How much force pushes the surfaces together (normal force)
- surface area *** (affects only a little)
3) Friction is a force that acts against the movement of the object (it slows the object down)
