Question

What is the meaning of word friction in terms of physics?

Answer 1

Definition. Friction is a catchall wordthat refers to any force that resists relative tangential motion (or intended motion). "Relative tangential motion" is a fancy way to say "slipping" or "sliding". Its direction is opposite the relative velocity (or intended velocity).


What is frictional force in physics?
This force is static friction force, which is the force exerted on the surface by another when there is no motion between the two surfaces. Static friction force acts in response to a forcetrying to cause a stationary object to start moving.

Answer 2

$\huge \leadsto\pmb{ \bf{ \orange{ \underline{FRICTION}}}}$

• Friction is a contact force, applied between two surfaces that have relation motion.

• Friction always opposes the relative motion by applying a force in opposite direction.

• It is a self adjusting force. It first increases with the application of external force and then becomes constant by attaining a maximum possible force.
