What is friction?
In this post, we apply Newton’s first two laws of motion to a variety of everyday situations, including both static and dynamic examples, and include the role played by friction, as a part of the Prelim Physics course under the module Dynamics and sub-part Forces, Acceleration and Energy.
Friction is a force between two surfaces that are sliding, or trying to slide, across each other. The equation of friction \vec{F}_{friction} = \mu \vec{F}_{N} , where \vec{F}_{friction} is frictional force, \vec{F}_{N} is the normal force, and \mu is the coefficient of friction.
The following video covers everything you need to know about friction and more.
