Question

What are static and kinetic frictions?​

Answer 1

Static friction is what keeps the box from moving without being pushed, and it must be overcome with a sufficient opposing force before the box will move. Kinetic friction (also referred to as dynamic friction) is the force that resists the relative movement of the surfaces once they're in motion .

Answer 2

--ANSWER--

Static friction:- The force applied to any body when at rest.

For example: a car in no motion.

: It is the most powerful friction.

Kinetic friction:- The force which acts between two moving objects is known as kinetic friction.

For example: A car in motion against road.
