Question

3. We prove that
(a) rolling friction is less than sliding friction
(b) sliding friction is less than rolling friction
(c) rolling friction is equal to sliding friction
(d) rolling friction is zero​

Answer 1

Answer:

(a) rolling friction is less than sliding friction

Answer 2

1. Rolling Friction and Sliding Friction

Sliding friction is the force that acts against two surfaces that are rubbing together. Rolling friction is less than sliding friction as the rolling of one body over another requires a smaller area of surface contact than sliding.

2. Rolling Friction and Sliding Friction

Sliding friction is the force that acts against two surfaces that are rubbing together. Rolling friction is less than sliding friction as the rolling of one body over another requires a smaller area of surface contact than sliding.
