Question
A smooth surface has ____.
- Less friction
- More friction
- Sometimes less and sometimes more
- All of these
Hint:
A smooth surface provides less resistance i.e. less friction.
The correct answer is: Less friction
A smooth surface has less friction.
- The friction on a surface depends on the texture of the surface.
- The friction on a rough surface is more.
- A smooth surface causes less friction since it provides less opposing force.
