M has various meanings in the Physics category. Discover the full forms, definitions, and usage contexts of M in Physics.
The 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.
