Question

Explain the action of rollers in reducing frictional force.

Answer 1

Rollers r a great way to reduce friction...friction increases if contact to the surface is more...in case of rollers the area of roller in contact with ground is less and thus it reduces friction effect....u might have noticed that ur vehicle runs slow if u have less air in ur tires.... This is because when air is less the tires become flat and more area of tires comes in contact with ground and thus friction increases and vehicle becomes slow...rate my answer please
