What is the definition of volume in physics?

Volume (symbolized V ) is a three-dimensional quantity representing amount or extent of physical bulk. The standard unit of volume in the International System ( SI ) is the meter cubed (m 3 ). Volume is usually measured or defined in Euclidean (flat) three-space in Newtonian (non-relativistic) physics. read more

There are formulas for calculating the volume of regular solid shapes. Another method of determining the volume of a solid is to measure how much liquid it displaces. Volume vs. Mass. Volume is the amount of space occupied by a substance, while mass is the amount of matter it contains. The amount of mass per unit of volume is a sample's density. read more

Control volume is an imaginary surface enclosing a volume of interest. The control volume can be fixed or moving, and it can be rigid or deformable. In order to determine all forces acting on the surfaces of the control volume we have to solve the conservation laws in this control volume. read more
