Usually different kinds of oils or lubrications.
lubrication decreases friction unless you're lubricating with sandpaper.
Decrease friction .
by using a lubricant to decrease the friction.
Friction will decrease if the coefficient of friction decreases. This can be caused by having a smother surface up to a point. (When two surface are TOO smooth the friction actually increases due to molecular attraction.)
OIL == ==
A friction block is a mechanical device used to increase or decrease friction in a system by applying pressure to a surface. It is commonly used in industrial settings to control the movement of objects or machines.
The liquid that reduces friction is called a lubricant. Lubricants are used to minimize the friction and wear between moving surfaces by forming a film that separates them.
Friction is decreased by means of lubrication.
Decrease friction.
Wax, due to it filling the pores that cause friction will reduce friction.
you don't.
Okay, there are three types of friction.Rolling Friction:asscociated with the rolling of a wheel or somthine circular along a surfaceStatic Friction: when 2 objects are rubbing against each otherKinetic friction: the friction involved when two objects are moving relative to each other and rub against each otherTo decrease friction i would use rolling. Rolling friction has less friction.HOPE THIS HELPS!!
