Question

Differentiate between rolling and sliding friction ?

Answer 1

Answer:

Rolling friction takes place when an object rolls on the surface. Sliding friction takes place when two surfaces are rubbed against each other. Rolling friction takes place due to the deformation of surfaces.

Answer 2

Answer:

SLIDING FRICTION: -When the surfaces slide over each other.

                                  -It is more than rolling friction.

                                  -Rolling friction takes place due to the deformation of surfaces.

ROLLING FRICTION: -When the surfaces roll over each other.

                                  -It is lesser than sliding friction.

                                  -Sliding friction takes place due to interlocking between microscopic surfaces.
