Friction Theory

Friction Theory suggests that a liquid's ability to flow or spread is influenced by internal resistance, known as viscosity, and the surface it contacts. When a liquid moves over a surface, friction opposes its motion, affecting how easily it spreads or adheres. Factors like temperature, surface roughness, and the liquid’s composition change this frictional force, thus impacting flow behavior. This understanding helps in applications like lubrication, painting, and manufacturing, where controlling how liquids flow and stick is essential for optimal performance.
