What is the force of friction ? write any two method to reduce friction.​

Answer 1

Answer:

Friction is the force that resists motion when the surface of one object comes in contact with the surface of another.There are several ways to reduce friction: The use of bearing surfaces that are themselves sacrificial, such as low shear materials, of which lead/copper journal bearings are an example. Replace sliding friction with rolling element friction, such as with the use of rolling element bearings.
