Question

6) Explain how does lubrication reduces friction ​

Answer 1

Answer:

Lubrication is another way to make a surface smoother.

A lubricant is a slippery substance designed to reduce the friction between surfaces.

You might use oil to stop a door from squeaking - the oil reduces the friction in the hinge.

Water can be used as a lubricant - think of how a floor becomes slippery after it has been mopped.
