ACTION

Action

In physics, action is an attribute of the dynamics of a physical system. It is a mathematical functional which takes the trajectory, also called path or history, of the system as its argument and has a real number as its result. Generally, the action takes different values for different paths. Action has the dimensions of [[energy|1]]ยท[[time|2]], and its SI unit is joule-second. This is the same unit as that of angular momentum.
