Laws of Motion

Question

Why is it difficult to move a bike with its brakes on? 

Answer

When the brakes of a bike are on, its wheels cannot rotate. They will simply skid. Thus, rolling friction will be converted into sliding friction which is comparatively larger. Hence, it becomes difficult to move the bike.
