What is viscosity ?

Viscosity is a measurement of how resistant a fluid is ,in attempting to move through it .

A fluid with low viscosity is said to be " thin " and a fluid with high viscosity , " thick " .

Example -----

Water has low viscosity as compared to honey , which is higher in viscosity .

That's  why when both are made to flow on ground , honey takes long time to cover the distance as was covered by water at the same time.
