what is frictional force class 9
Answers
correct answer
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. ... Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

Explanation:
Frictional force is the opposing force formed between two surfaces that are attempting to move in the same direction or in opposite directions. A frictional force's principal purpose is to generate resistance to the mobility of one surface over another. Heat is produced via friction. When we rub our hands together, friction occurs, resulting in the production of heat.
Friction force
f = μN
f = Friction force
μ = Coefficient of friction
N = Normal force
