Accounting events have not only three intrinsic elements (debit, credit, and size) but also a multitude of properties, some of which are nonmonetary and are hence beyond monetary measurement and interpretation. Examples of such properties include dimensionality, duality, force, power, quality, and informativeness, among others. The dimensionality and duality of accounting events were examined in Chaps. 1 and 2 . This chapter discusses two additional properties—force and power—of accounting events in two- and three-dimensional geometric settings. It does so with the transaction examples in Chap. 3 for illustrations. Research on force and power is well established in other fields of study such as physics, engineering, and sociology, to name a few. They are often employed to explain how the properties of an object, a thing, or a phenomenon exist or work. Such, however, is not the case in accounting although accounting events have force and power as their intrinsic properties.
