Question

what is frication and what is roling frication

Answer 1

Answer:

Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface. ... This coefficient of rolling resistance is generally much smaller than the coefficient of sliding friction.

Explanation:

Answer 2

Friction:

The resistance that one surface or object encounters when moving over another.

Rolling Friction:

Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation of the wheel, roadbed, etc. is recovered when the pressure is removed.
