Projections that allow the cell to move or to move substances along the surface of the cell are called cilia and flagella. Flagella is a single long hair that allows the cell to swim. Cilia are several projections used for movement across the cell surface.

Friction is still there and gravity causes that, if there is no gravity there is no friction. Only in your case friction is reduced because there is less drag because of the polished surface it is not harder to move along the surface. (assuming there is a force moving the object on top of the surface)
streamlining is important as it helps in reducing friction and so the body can move smoothly.
Hands of a clock move in a clockwise direction. Most hands move with pulses every second and minute, while some move smoothly without any pulses in between.
Snails move by contracting its body muscles and move along the surface with this gooey thing called "slime".It moves along the surface so smoothly and it leaves a little trail behind,so it doesn't have any problem traveling.That is how the snail generate its power of motion and across the surface like that.
The act of moving smoothly along a surface while remaining in contact with it

it means to move smoothly
A wheel is circular to reduce friction with the road surface, and to allow a vehicle to move smoothly forward.

To move along a surface by revolving or turning.
the surface of the earth is divided into pieces called tectonic plates.when these plates move and rub against each other,they don't move smoothly.when the plates don't move smoothly earthquakes result.
