Question

Why do pieces of luggage fitted with rollers​

Answer 1

$\mathcal\red{Answer}$

⟹When one body rolls over the surface of another body, the resistance to its motion is called the rolling friction.

Rolling reduces friction. It is always easier to roll than to slide a body over another.

That is the reason it is convenient to pull the luggages fitted with rollers.
