Question

What is friction?What is mass?​

Answer 1

Answer:

Friction: Friction is a force that opposes the movement of an object. It depends both on the mass of the object and the surface that it moves on. ... Generally, rough surfaces have greater friction coefficients and smooth surfaces have smaller friction coefficients.

Answer 2

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.

Mass is a property of a physical object that quantifies the amount of matter it contains. Unlike weight, the mass of something stays the same regardless of location.
