What is cause of Friction ?
Answers
Answer:
Causes of Friction:
Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. Adhesion is the molecular force resulting when two materials are brought into close contact with each other
Friction happens when two surfaces move over one another. Also, it is a force that resists the motion of an object. Moreover, it causes motion energy to be lost in the form of heat. Besides, we use the coefficient of friction to describe how two surfaces interact. Furthermore, the Greek letter ‘mu’ (μ), and it is unitless. In addition, the force of friction isη times the normal force on an object. Most noteworthy, the unit of friction is Newton (N).
Friction = (coefficient of friction) (normal force)
f = μη

Explanation:
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.
