Question

Why it is convenient to pull luggage bags fitted with rollers?

Answer 1

It is because rolling friction is convenient than sliding friction.

If we slide something, The contact surface will be more and the friction will also be more.

If we roll something, the contact surface will be less and the friction will also be less.

So, it is convenient to pull a luggage bags with rollers.

Answer:

The friction acting when an object rolls over another object is called rolling friction. It is easier to pull a luggage fitted with rollers than to drag it. Rolling decreases the friction and makes movement of things easier. This is why luggages are fitted with rollers. Hopes it helps!
