Friction
Question | Answer |
---|---|
what is friction | a force that opposes motion between 2 surfaces that are in contact |
what is static friction | when a force is applied to an object but does not cause the object to move |
what is sliding friction | friction between 2 things that are moving |
what s rolling friction | friction between a rolling object and the object it rolls on |
kinetic friction | friction applied to a moving object |
kinetic force is always LESS than static friction | molecular forces form on stationary object friction depends on 2 surfaces involved |
