Yes, because with out friction everything and/or every one would be slipping on the ground.
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.
Friction is essential to the way we live and life as a whole. An example of friction is sliding down a hill on a sled or even just our joints rubbing together or even the wheels on a rolling on the ground
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.
