Question

Which type of surface produce (a)least friction and (b)too much friction ?

Answer 1

a. smooth and polished surface
b. rough and uneven surface

i hope this helps:))

Answer 2

Surfaces that are rougher have greater friction than smoother surfaces. Friction is reduced on smooth surfaces.

The rough surface produces too much friction :

• Surfaces that are rougher have greater friction than smoother surfaces. That's why sand is used to de-ice frozen sidewalks and highways.

• With shoes, you can't slide as far over the ice as you can with skate blades. The rougher the soles of the shoes are, the more friction they create, which slows you down.

Smooth surfaces produces less friction :

• Friction is reduced on smooth surfaces. This is because a rough surface provides greater resistance to an item moving across it than a smooth surface.
