Question

frictional force explanation​

Answer 1

Answer:

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.

Answer 2

$\huge\underline\mathfrak{Answer!!}$

Explanation:

Frictional force refers to the force generated by two surfaces that contact and slide against each other. It is the force that opposes the motion of the object. It is easy to explain that if the two bodies contact with each other then friction is developed.
