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.
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.
Tornadoes have caused bridges to collapse on a number of occasions. In some cases pieces of bridges have been carried away by tornadoes.
As water in the stream channel flows, it encounters friction; the friction slows the forward movement. The shape,size, and roughness affect the amount of friction. High friction slows the stream significantly.
