Answer 2

hello dear

It is always easier to roll a body then to slide to over a surface. So it is convenient to pull at the luggage fitted with rollers. When one body rolls over the surface of another body , the friction offered is colled rolling friction . So this is the reason behind rollers are used for transporting luggage .
