Answer:
Sliding has greater friction than rolling

The sliding is replaced by rolling in most of the machine because in sliding the friction or frictional force is greater than rolling due to this reason the machine does not move easily and consume more energy but in rolling the friction is more and more less than sliding and its moves very easily and its consume less amount of energy.
