BRAINCAKEInvestigating Viscosity Changes with Temperature
The viscosity can be calculated by allowing small spherical objects of known weight to fall through a fluid until they reach terminal velocity.
The masses of the balls are measured using a balance and the diameters of the balls are measured using Vernier callipers
The density of the balls is calculated using

Key terms in this lesson
- terminal velocity
- The maximum, constant velocity reached by an object falling through a fluid when the resultant force on it becomes zero.
- viscosity
