Answer 1

Answer:

Hola.

Here is your answer mate______☺️

Explanation:

Theoretically, the contact surface in perfectly rigid bodies is zero. But, in practice due to deformation, there appears a small contact surface which is quite small compared to sliding surfaces that rub on each other. That's why it is easier to roll than to slide.
