Question

How does oiling or lubricant help in reducing friction?

Answer 1

Answer:

oiling and lubricant help in reducing friction because they prevent the direct driving of things

Answer 2

When some lubricants such as oil or grease is applied to surfaces some of the lubricant sticks to the sliding surfaces . In this way the sliding surfaces are separated by a thin layer of oil or grease and the interlocking of irregularities is greatly reduced. Thus movement becomes smooth.
