Action (physics)
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 •, and its SI unit is joule•second. This is the same units as angular momentum.

Famous quotes containing the word action:
“Let the will embrace the highest ideals freely and with infinite strength, but let action first take hold of what lies closest.”
—Franz Grillparzer (1791–1872)
