ActivityMeasure | **is a kind of** TimeDependentQuantity | |

TimeDependentQuantity | *documentation* A UnaryConstantFunction of continuous *time*. All instances of this Class map a *time* quantity into another ConstantQuantity such as temperature. For example, 'the temperature at the top of the Empire State Building' is a TimeDependentQuantity since its value depends on the *time* | |
