Lubrication is the use of oil and grease to increase friction in a vehicle's moving parts
lubrication
You can reduce friction by using lubrication, like grease for bearing, sewing machine oil etc.
Depends what you want to increase/decrease friction on. If is like a weight on the floor.. Then to increase the friction all you have to do is increase the weight, To reduce it you either reduce the weight or get a smoother surface, or maybe a cloth in-between the floor and the weight.
Grease reduces friction because the two original materials are no longer touching each other. If you have a piece of steel rubbing against another piece of steel then there is friction between them. If grease is on the surfaces then you have molecules of grease rubbing against other molecules of grease. Grease is slippery stuff as it has a very lowCoefficient of friction. Every material has a coefficient of friction but with steel it is quite high. Teflon is very very low. Proper name polytetrafluorethylene or ptfe.

ball bearings and lubrication.
Grease and oil is used in machinery to prevent the moving parts from wearing out too soon due to friction.
oil and grease is used in vehicles to reduce friction.
Lubricate means to oil or grease to provide smooth movement and minimize friction.

to reduce friction
For lubrication. To reduce friction and heat buildup which would quickly damage the engine otherwise.
The most common method is lubrication of some sort: grease, silicone etc.
Apply lubrication such as oil and grease. Ensure both faces of the materials that are in contact are polished to remove abrasive surface. (this will still cause friction but it is less that a course surface)
