Question

The rolling ball eventually comes to rest . Similarly, if we stop pedalling a bicycle,it gradually stops. What causes a change in their state of motion ? Explain

PEDALING CYCLE IS THE SAME

Answer 2

In this both cases ball frictional force will act opposite, motion will be reduced,

and the stop pedalling a bicycle is same
