1. It is easier to push a heavy object on a polished wooden because then the box will be easier to push across the floor.
There is more friction, this ensures your feet do not slide

Friction is greater on a carpet, so your shoes or feet can grip better.
Friction and drag
Ice has a smoother surface so causes less friction
You can see yourself in smooth and polished surfaces because the surface is clean and not blurry. Also, you can't see yourself in certain smooth and polished surfaces, such as tan desks.
Assuming the rugosities are not so large to be trip hazards, the rough surface has the higher friction, hence drag, between floor and shoe sole.

Depends on the surface, sandpaper usually.
smooth:- surface of the mirror , floor of the room when polished , surface of wet soaps,glazed tiles & surface of a oily pot . rough :- soles of shoes , surface of a ply board , unpainted wall, surface of a brick & surface of tyres .

A fractured surface--rough. A polished or worn surface--smooth.

Because it is a metal and can be polished to a smooth shiny surface.
Smooth and shining; reflecting luster from a smooth surface; highly polished; lustrous; as, glossy silk; a glossy surface., Smooth; specious; plausible; as, glossy deceit.
Depends on the surface, sandpaper usually.
The preparation of the surface before polishing and ultimately the application and buffing up of the polish.
Brushed nickel has a brushed dull finish. Polished nickel has a smooth shiny surface.
Ice erosion can do this as can aeolian erosion (desert varnish).
