Lubricants are used to reduce friction, as well as grinding the surfaces in contact until they are very smooth.
True
Friction is the act of one surface rubbing against another. To reduce friction, use something that offers a small amount of friction. Smoother substances reduce friction. A way to reduce friction is to use something which offers a small amount of friction. For example, you could use something like plastic or glass. Water, most liquids and different types of oil reduce friction. Powder, oil and grease are used in between surfaces to also reduce friction.
No, sand does not reduce friction but increase friction.
Lubrication to reduce friction. To increase friction step on the brakes.
OIL == ==
use a bio-degradable liquid lubricant on the longitudinal joints
Oil is used to reduce friction.
Lubricant- something that that lubricates.
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.

yes.
True
There is a thick liquid produced in the joint spaces to cushion and reduce friction. This viscous fluid is called synovial fluid.
To reduce unwanted friction.
To reduce the coefficient of friction.
