Question

We prove that________.
(i) rolling friction is less than sliding friction.
(ii) sliding friction is less than rolling friction.
(iii) rolling friction is equal to sliding friction.
(iv) rolling friction is zero. ​

Answer 1

Answer:

rolling friction is less than sliding friction

Answer 2

Answer:

Rolling friction is less than sliding friction

Explanation:

There are 3 types of friction

Static friction>Sliding friction>Rolling friction

Interlocking is weaker in rolling friction than sliding friction so, Rolling friction<Sliding friction
