Answer:

reduce friction

Explanation:

Lubricants are needed to reduce the friction between two bodies in contact with one another.

Frictional force is a force that opposes the motion of a body. As a body moves forward, friction acts in an opposite direction.

  • Lubricants are used to reduce and remove friction
  • Unfortunately, without friction, motion cannot be controlled.
  • Lubricants only reduces friction between two bodies.
  • As friction reduces, a body moves more readily and easily.
