Question

what is friction define ​

Answer 1

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

Answer 2

Answer:

Formula

Friction force

f = \mu N

f = friction force

\mu = coefficient of friction

N = normal force

Explanation:

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.

Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. ... Fluid friction occurs in fluids, which are liquids or gases.
