Question

Can someone explain slip friction.

If a ball slips down a plane, it is known that the surface is frictionless. however that is not the case in real life. Does slip friction occur on surfaces with friction due to other phenomena/reasons

Answer 1

i'm currently looking at stick-slip friction... is this possibly what i'm looking for?

Answer 2

A rolling ball is static friction.

Answer 3

Dragging your little sister across the hardwood floor is kinetic (slip) friction

Answer 4

yes but it's possible for a ball in real life to slip and roll at different points in the plane correct?

Answer 5

what cause this change... does it have to do with the material of the board be not uniform?

Answer 6

stick-slip friction is a combination of the two. It occurs in a dynamic system usually with a changing force.

Answer 7

Elaborate what do you mean by slip and roll at different points in the plane?

Answer 8

does a ball rolling down a ramp experience both slip and static?

Answer 9

no not under ideal condidtions, just static

Answer 10

if the surface coefficient was not uniform or if the ramps angle from the horizontal was changing it could be possible to observe slip-stick.
