Answer 1

Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism.

Friction is the force that resists motion when the surface of one object comes in contact with the surface of another. The mechanical advantage of a machine is reduced by friction, or in other words, the ratio of output to input is reduced because of friction.
