Question

It is difficult to move a bike with its brakes on because (a) rolling friction will be converted to sliding friction (b) sliding friction will be converted to rolling friction les rolling friction will be converted in to static friction (d) none of these​

Answer 1

Answer:

When we try to move a bike with its brakes on, the wheels of the bike will skid to a different direction. This is because there is sliding friction, which is larger than rolling friction. Therefore, it is hard to move a bike or a cycle with its brakes on.

Answer 2

Explanation:

option c rolling friction will be converted into static friction

because the tires of the bike were rolling before we apply brakes and then as we apply brake then the tires that was rolling come at rest so this option is correct
