👉 In physics, a viscous medium refers to an object or substance that exhibits a tendency to resist the motion of fluid particles. This behavior is characterized by viscosity, which is a measure of how much resistance there is to flowing fluids. Viscosity can be divided into two main types: dynamic and thermal. Dynamic viscosity is related to the rate at which pressure changes with time, while thermal viscosity is related to the heat capacity per unit volume of the material. The presence of viscous materials in an object
