Question

Static friction is greater than sliding friction. Give reason

Answer 1

the static friction is greater then sliding friction
bcz friction is due to actual molecules of 2 bodies in contact ( means the surfaces which are contact create friction by the bond formation between the molecules in contact).
now when body is at rest their is more bond formation bcz of more interaction of molecules while when a body is in sliding motion their is bond formation for less time which keep on breaking bcz of less time of interaction of molecules .
hence, static friction is greater then sliding friction.
