Question

A body needs a force F₁ just to start motion on a surface, a force F₂ to continue its motion and a force F₃ to roll on the surface. What is

the static friction

sliding friction and

rolling friction ? State whether F₂ is equal, less than or greater than (1) F₁ and (2) F₃.

Solution

F₁ = Static friction

F₂ = Sliding friction

F₃ = Rolling friction
F₁ > F₂ > F₃
F₂ is less than F₁ but greater than F₃.
