Question

A flat tyre is harder to roll than an inflated tire because ______.

विकल्प

• It is heavier

• It deforms more, increasing the contact area and friction

• It has less air inside

• It rotates faster

Answer 1

A flat tyre is harder to roll than an inflated tyre because it deforms more, increasing the contact area and friction.

Explanation:

A flat tire loses its shape, increasing the contact area with the ground, which increases friction resistance.
