Which is true for rolling friction ( _r ) , static friction ( _s ) and kinetic friction ( _k ) :

Options

  1. A_s _k _r
  2. B_s _k _r
  3. C_s _k _r
  4. D_s _r _k

Correct answer

A. _s _k _r

Step-by-step solution

Static friction is always greater than kinetic friction, and rolling friction is less than kinetic friction, so _s _k _r
