what is friction ? law of friction
Answers
THE FIVE LAWS OF FRICTION. When an object is moving, the friction is proportional and perpendicular to the normal force (N) Friction is independent of the area of contact so long as there is an area of contact. The coefficient of static friction is slightly greater than the coefficient of kinetic friction
FRICTION -Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

Explanation:
Friction. :- Friction is the resistance to motion if one object moving relative to another , it is not a fundamental force , like gravity and electomagnatism. electromagnetic attractions between charged particles in two touching particles.
LAW :-- 1 when the object is moving the frictional is proportional and perpendicular to the normal force.
2 Friction is independent on the area of Contect
3. The cofficient of static friction is slightly greater than the cofficient of kinetic friction.
