Scientific & EducationalThe quantity of matter in a body as measured by the ratio of the force required to produce a given acceleration, to the acceleration. A property of all matter. It is measured in, for example, grams. Mass is independent of gravity, unlike weight which depends on gravity. The quantity of matter in a body. It can be determined by measuring the force of gravity (weight) acting on it and dividing this by the gravitational acceleration at that point. Thus, the mass of a given body remains the same everywhere, while its weight changes with the gravitational attraction.
Scientific & EducationalIn fluid dynamics, the Mach number is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound M=u/c where, M is the Mach number, u is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and c is the speed of sound in the medium.
