Question

1. choose the best answer. rough, bumpy surfaces have __ friction than smooth surfaces. more less 8) choose the best answer. the force of friction __ when there is less surface area between objects. decreases increases

Explanation:

Friction is related to surface - texture and surface - area. Rougher surfaces have more irregularities, leading to greater friction. The force of friction is independent of the surface area between objects in the case of sliding friction.

Answer:

1. more
2. remains the same (neither of the given options is correct as friction force for sliding friction is independent of surface - area, but if we assume this is a basic - level question with a simplified view and no other options, we can't choose from the given ones accurately)
