Force friction is a contact forcethe occurs when two surfaces

try to slide passed each other.Friction can get an objectmoving or friction can bringan object to rest .

Force Friction

The friction forceis directly relatedto force Normal

.

That means the morethe surfaces are

pushed together, the greater theforce of friction
