Question

why sliding friction is greater than rolling friction write two lines

Answer 1

riding friction is greater than rolling friction in two lines because sliding friction needs more magnitude of force than a rolling friction

Answer 2

Rolling friction is the resistance to motion experienced by a body when it rolls upon another. It is much less than sliding frictionfor same pair of bodies. When one body rolls upon another, there is theoretically no sliding or slip between them. And if both are perfectly rigid, there is no surface of contact.
