Why are luggage fitted with rollers?

Correct option is C

The correct answer is (c) Wheels reduce friction and rolling makes the movement smooth and easy.
· Rollers or wheels on luggage are designed to reduce friction between the luggage and the surface it moves on. This reduction in friction makes it easier to move the luggage with less effort.
· Rolling friction, which occurs when an object rolls over a surface, is significantly lower than sliding friction, which occurs when an object slides over a surface.
· This is why wheeled luggage is much easier to maneuver compared to carrying or dragging it, especially over long distances or on smooth surfaces.

Information Booster:
· Rollers obstruct easy and smooth movement: This statement is incorrect because rollers are meant to facilitate smooth movement, not obstruct it.
· Rollers give grip to luggage so that movement is tough: This is incorrect. Rollers are designed to make movement easier, not tougher.
· Rolling friction is higher than sliding friction. Hence, luggages are fitted with rollers: This is incorrect. Rolling friction is lower than sliding friction, which is why rollers are used to make movement easier.
