You can change friction by the material. e.g ice, low friction. carpet high friction.Or you could add a lubricant :D
No,of course not, the friction between the basketball and the grass would make the ball bounce less.
The friction on a hinge needs to be small at the pivot point where the hinge rotates. This allows smooth movement and prevents the hinge from sticking or getting stuck. However, in other parts of the hinge, such as the pins or brackets, a small amount of friction may be desirable to provide stability and prevent excessive movement.
By making the surface rough for increasing friction....... use any lubricating material to reduce the friction.. use rollers to decrease the friction force.. make less contact between 2 connecting materials..
If you were roller-skating you don't need friction because it slows you down. Well you want friction between the wheels and the floor (so you do not slip sideways) but not between the wheel and the axel (thats why you have ball bearings there to reduce rolling friction). If you are ice skating you do not want friction between the blade of your skates and the ice.

when 2 surfaces rube or slide together the more smooth the less friction
Air resistance against the bob and string and friction in the pivot make the amplitude of a simple pendulum decrease.
you can either make your own or you could download effects
Gravity doesn't make a pendulum stop. Air resistance and friction in the pivot are the things that rob its energy. If you could eliminate those and leave it all up to gravity, the pendulum would never stop.
Use Cd's as wheels to make less friction
use bigger wheels and use less friction on the ground make it weigh less

because you might make it dirty because you might make it dirty

You have to make it.
