Answer 1

Answer:

Explanation:

ubricants. A common way to reduce friction is by using a lubricant, such as oil, water, or grease, which is placed between the two surfaces, often dramatically lessening the coefficient of friction. The science of friction and lubrication is called tribology.

Answer 2

Answer:

The number and height of the asperities on the surfaces dramatically affect the friction between the surfaces. It is the job of the lubricant to keep these asperities apart and prevent them from contacting each other, thus lowering or eliminating metal-to-metal contact and friction.
