Same way it affects all structures - heat and sound is produced, and some material is lost due to ablation (being rubbed away).
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.
there could be friction inside the motor. there is friction on the wheels of the scooter and the ground. there is air friction when you move on a scooter.
answer it yourself ;)
Gravity and friction there are others also like magnetism for example..
Satellites in a low orbit, however, are slowed by friction with Earth's atmosphere.
A variable that has no affect on friction is Inertia
Two objects of different weights placed on a glass surface and a wooden surface
Carpenters builds or repairs wooden structures.

friction
We would need to know what the friction is to affect to respond to this question.
ice can affect friction
Gravity and static friction.
Speed does not affect the force of friction.
Wooden match and car brakes
There is the metro Parasol in spain
Carpenter ants burrow and dig into wooden structures to establish their colony. These leads to a porous interior in the wood which will eventually degrade under stress.
