Viscosity

Real World Example

Imagine trying to move through a crowded room where everyone is tightly packed together. Just as you struggle to weave your way through people because they resist your movement, a fluid with high viscosity resists flowing easily. In this analogy, the crowded room represents a viscous fluid, where the density and interaction of people are like molecules in the fluid, and your difficulty in moving is akin to the fluid's resistance to flow.
