1) Rough material mostly does not have a plane surface , they are often in zig zag pattern.
2) When we try to move any object in a rough surface , it takes longer time to cover the distance because of more friction.
3) To convert rough surface into smooth surface, lubricants can be used.
1) Smooth materials are plane.
2) When we move anything on smooth surface, it covers the distance in shorter span of time due to less friction.
3) Some of the ways to convert smooth surface into rough surface are spreading pebbles on the surface , destroying the uniform coat on the surface etc.
