Question

a 1 A body needs a force F just to start motion on surface, a force F2 to continue its motion and a force Fz to roll on the surface. What is (i) the static friction (ii) sliding friction and (iii) rolling friction ? State whether F2 is equal, less than or greater than (i) F, and (ii) Fz ?​
