Question

Between a smooth and a rough surface, which of the two surfaces is easier to slide and why?​

Answer 1

Hello There!

Smooth Surfaces are easier to slide over. That's true.

Take an object and slide it across a rough surface. Now, slide the same object across a smooth surface.

What do you see?

I expect you wil find out that smooth surfaces are easier to slide over.

Reason:

Smooth surfaces have less friction than rough ones.

Hope it helps!

Answer 2

When two surfaces slide against each other, a force called friction makes them stick very slightly together. Smooth surfaces, like ice and glass, are easy to slide over

Step-by-step explanation:

They create very little friction. Rough surfaces like rock and sand create much more friction, and are easy to grip on to.
