In [[mechanics]], coordinates of moving bodies are functions of time. For example, the classical equation for a falling body; its height at a time ''t'' is
:<math> h(t) = h_0 - \frac12 g t^2 </math>
(here ''h''<sub>0</sub> is the initial height, and ''g'' is the gravity of Earth). The height changes in time, but the function ''h'' does not.

In mechanics, coordinates of moving bodies are functions of time. For example, the classical equation for a falling body; its height at a time t is

(here h0 is the initial height, and g is the gravity of Earth). The height changes in time, but the function h does not.
