Answer 2

Answer:

It's false.

Explanation:

The relationship between surface texture and friction between two dry sliding surfaces is more complex than it first appears. ... Making a surface rougher or smoother may not always affect the sliding friction. In addition to this, for certain textures and materials, making a surface smoother reduces friction.

As the contact pressure increases, the friction does not rise proportionately, and when the pressure becomes very high, friction increases rapidly until seizing takes place.
