Which physical quantity is calculated by multiplying a body’s mass by its velocity?
Physical quantity space, momentum, torque, position, and length (just to name a few) are all found to be experimentally variant in some particular scale and system. Additionally, the notion that it is possible to measure "physical quantities" comes into question, particular in quantum field theory and normalization techniques. As infinities are produced by the theory, the actual “measurements” made are not really those of the physical universe (as we cannot measure infinities), they are those of the renormalization scheme which is expressly dependent on our measurement scheme, coordinate system and metric system.

Physical quantity Physical quantity A physical quantity is a physical property of a phenomenon, body, or substance, that can be quantified by measurement. A physical quantity can be expressed as the combination of a magnitude expressed by a number – usually a real number – and a unit: formula_1 where formula_2 is the magnitude and formula_3 is the unit. For example, (the mass of the neutron), or (the speed of light). The same physical quantity formula_4 can be represented equivalently in many unit systems, "i.e." formula_5. Symbols for quantities should be chosen according to the international recommendations of ISO/IEC 80000, the IUPAP
