Friction affects most every thing. In a mechanical metronome you would not need a power source if there were no friction.
No, because there's a resoring force from the coil.
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.
A metronome.
Tempo is measured in the number of beats per minute. Metronomes were traditionally used to do this, but it is more common to use music sequencers to do so now.
It is a metronome.
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.
