Question

A body needs a force F1 just to start motion on a surface, a force F2 to continue it's motion and a force F3 to roll on the surface. What is ( 1) the static friction (2) sliding friction and (3) rolling friction? state whether F2 is equal, less than or greater than (1) F1 and (2) F3.​

Answer 1

Answer:

Explanation:Static Friction - th friction which acts when body is at rest .

Example - A book kept on a table .

Sliding friction -The friction which acts when one surface slides over another surface .

Example - A shoot case is slides on a smooth surface .

Rolling Friction - When one surface Rolles over another surface by the use of wheels , ball bearing etc.

Example - trolly bags attached with wheels ,vechils have wheels
