WebNewton’s Law of Viscosity What is viscosity? Viscosity is a physical property of fluids (liquids and gasses) that pretty much measures their resistance to flow. On a more fundamental level, the term “flow” refers to molecules moving along due to some net force. The more a fluid is able to withstand that force, the greater its viscosity.
