friction opposes the force causing the body to move. fiction is the reason why you are unable push very heavy objects on normal surfaces. if an object is on a truly frictionless surface, you will be able to push it left to right, side to side regardless of how heavy it is.
because of a source of movment
A variable that has no affect on friction is Inertia

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.
