Angular momentum is a vector quantity (more precisely, a pseudovector) that represents the product of a body's rotational inertia and rotational velocity (in radians/sec) about a particular axis. In physics, energy density is the amount of energy stored in a given system or region of space per unit volume.It is sometimes confused with energy per unit mass which is properly called specific energy or gravimetric energy density.. Often only the useful or extractable energy is measured, which is to say that inaccessible energy (such as rest mass energy) is ignored. relative density n (Units) the ratio of the density of a substance to the density of a standard substance under specified conditions. However, buoyancy varies on the basis of body composition, lung inflation, muscle and fat content, centre of gravity and the salinity of the water.
