Solution

The correct option is B
False

Wheels are added to trolleys to reduce the friction. As rolling friction is less than sliding friction, by adding wheels to trolleys the friction is reduced.

In rolling, less body surface is in contact compared to sliding, hence the friction is less.

Q. Sliding friction is always less than rolling friction.

Which of the following statements is incorrect?
(a) static friction is greater than rolling friction
(b) sliding friction is less than rolling friction
(c) rolling friction is less than static friction
(d) static friction is greater than sliding friction

Since rolling friction is less than sliding friction, sliding friction is replaced with rolling friction in most machines using ball bearings.

Ball bearing is a device which usually converts:
(a) rolling friction into sliding friction
(b) static friction into sliding friction
(c) sliding friction into rolling friction
