Question & Answer
Choose the Best Answer
Rougher surfaces generally increase friction due to greater interlocking of surface features.
Smoother surfaces always result in higher friction regardless of the materials.
Surface roughness has no impact on friction; only the materials' chemical properties matter.
Friction is solely determined by the weight of the materials in contact with each other.
Understanding the Answer
Let's break down why this is correct
A rougher surface has many bumps and valleys. Other options are incorrect because The idea that smoother surfaces always give more friction is a mistake; Thinking that only chemical properties matter ignores texture.
