friction
We would need to know what the friction is to affect to respond to this question.
ice can affect friction
Speed does not affect the force of friction.
An airplane flying through the air, a swimmer diving into a pool etc.
surface friction and sliding friction
Friction will slow it down
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.
the smoother a surface is, the less friction it produces.
The nature of the surface. A measure of this is the coefficient of friction.
