A body needs a force $F_{\mathit{1}}$ just to start motion on a surface, a force $F_2$ to continue its motion and a force $F_3$ to roll on the surface. What is (i) the static friction (ii) sliding friction and (iii) rolling friction? State whether $F_2$ is equal, less than or greater than (i) $F_1$ and (ii) $F_3$.
