Gravity vs. Magnitude — What's the Difference?

Gravity (from Latin gravitas 'weight'), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are attracted to (or gravitate toward) one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.

Greatness of rank or position

The force that attracts a body towards the centre of the earth, or towards any other physical body having mass.

Greatness in size or extent

Extreme importance; seriousness

Greatness in significance or influence

Solemnity of manner

The brightness of a celestial body on a numerical scale for which brighter objects have smaller values. Differences in magnitude are based on a logarithmic scale that matches the response of the human eye to differences in brightness so that a decrease of one magnitude represents an increase in apparent brightness by a factor of 2.512. Also called apparent magnitude.

The natural attraction between physical bodies, especially when one of the bodies is a celestial body, such as the earth.

A unit on such a scale of brightness.

See gravitation.

A number assigned to a quantity so that it may be compared with other quantities.

Grave consequence; seriousness or importance

A property that can be described by a real number, such as the volume of a sphere or the length of a vector.

Solemnity or dignity of manner.

(Geology) A measure of the amount of energy released by an earthquake, as indicated on the Richter scale.

The state or condition of having weight; weight; heaviness.

The absolute or relative size, extent or importance of something.

The state or condition of being grave; seriousness.

(countable) An order of magnitude.

(music) The lowness of a note.

(mathematics) A number, assigned to something, such that it may be compared to others numerically

(physics) The force at the Earth's surface, of the attraction by the Earth's masses, and the centrifugal pseudo-force caused by the Earth's rotation, resulting from gravitation.

(mathematics) Of a vector, the norm, most commonly, the two-norm.

Gravitation, the universal force exercised by two bodies onto each other.

(astronomy) A logarithmic scale of brightness defined so that a difference of 5 magnitudes is a factor of 100.

(physics) Specific gravity.

(uncountable) The apparent brightness of a star, with lower magnitudes being brighter; apparent magnitude

The state of having weight; beaviness; as, the gravity of lead.

(countable) A ratio of intensity expressed as a logarithm.

Sobriety of character or demeanor.

(seismology) A measure of the energy released by an earthquake (e.g. on the Richter scale).

Importance, significance, dignity, etc; hence, seriousness; enormity; as, the gravity of an offense.

Extent of dimensions; size; - applied to things that have length, breadth, and thickness.

The tendency of a mass of matter toward a center of attraction; esp., the tendency of a body toward the center of the earth; terrestrial gravitation.

That which has one or more of the three dimensions, length, breadth, and thickness.

Lowness of tone; - opposed to acuteness.

Anything of which greater or less can be predicated, as time, weight, force, and the like.

(physics) the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface;

Greatness; grandeur.

A manner that is serious and solemn

Greatness, in reference to influence or effect; importance; as, an affair of magnitude.

A solemn and dignified feeling

See magnitude of a star, below.

The property of relative size or extent;

A number assigned to the ratio of two quantities; two quantities are of the same order of magnitude if one is less than 10 times as large as the other; the number of magnitudes that the quantities differ is specified to within a power of 10

Relative importance;
