Question

write an effects of rollers on friction

Answer 1

The rollers decreases the friction, as the area is decreased that gets in touch with floor and experience friction, the rate of friction decreases and makes it easy for the objects to move around with the help of rollers due to lower stopping force. the wearing out of object also gets less due to this 

Answer 2

Explanation:

A wheel reduces friction by allowing the contacting surfaces to roll rather than to drag or slide over each other. By reducing friction, a wheel can enable you to use less force to move an object. The less force you use to move an object, the easier your work becomes.
