Answer 1

Answer:

Friction is the force that resists motion when the surface of one object comes in contact with the surface of another.

A contact force is any force that requires contact to occur. ... Contact forces are often decomposed into orthogonal components, one perpendicular to the surface(s) in contact called the normal force, and one parallel to the surface(s) in contact, called the friction force.

Answer 2

Answer:

Answer:Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
