Momentum vs. Energy

(physics) (of a body in motion) The tendency of a body to maintain its inertial motion; the product of its mass and velocity.

The impetus, either of a body in motion, or of an idea or course of events. (i.e: a moment)

The quantity of motion in a moving body, being always proportioned to the quantity of matter multiplied by the velocity; impetus.

Essential element, or constituent element.

Example: ‘I shall state the several momenta of the distinction in separate propositions.’;

A property of an activity or course of events, viewed as analogous to forward motion or to physical momentum (def. 1), such that the activity is believed to be able to continue moving forward without further application of force or effort; - often used to describe an increase in the acquisition of public support for a purpose; as, as, the petition drive gained momentum when it was mentioned in the newspapers.

an impelling force or strength;

Example: ‘the car's momentum carried it off the road’;

the product of a body's mass and its velocity;

Example: ‘the momentum of the particles was deduced from meteoritic velocities’;

In Newtonian mechanics, linear momentum, translational momentum, or simply momentum (pl. momenta) is the product of the mass and velocity of an object.

The impetus behind all motion and all activity.

The capacity to do work.

(physics) A quantity that denotes the ability to do work and is measured in a unit dimensioned in mass × distance²/time² (ML²/T²) or the equivalent.

An intangible, modifiable force (often characterized as either 'positive' or 'negative') believed in some New Age religions to emanate from a person, place or thing and which is (or can be) preserved and transferred in human interactions; shared mood or group habit; a vibe, a feeling, an impression. aura.}}

A measure of how many actions a player or unit can take; in the fantasy genre often called magic points or mana.

Example: ‘action points’;

Internal or inherent power; capacity of acting, operating, or producing an effect, whether exerted or not; as, men possessing energies may suffer them to lie inactive.

Example: ‘The great energies of nature are known to us only by their effects.’;

Power efficiently and forcibly exerted; vigorous or effectual operation; as, the energy of a magistrate.

Strength of expression; force of utterance; power to impress the mind and arouse the feelings; life; spirit; - said of speech, language, words, style; as, a style full of energy.

Capacity for performing work.

(physics) the capacity of a physical system to do work; the units of energy are joules or ergs;

Example: ‘energy can take a wide variety of forms’;

an exertion of force;

Example: ‘he plays tennis with great energy’;

enterprising or ambitious drive;

Example: ‘Europeans often laugh at American energy’;

an imaginative lively style (especially style of writing);

Example: ‘his writing conveys great energy’;

a healthy capacity for vigorous activity;

Example: ‘jogging works off my excess energy’; ‘he seemed full of vim and vigor’;

the federal department responsible for maintaining a national energy policy of the United States; created in 1977

In physics, energy is the quantitative property that must be transferred to a body or physical system to perform work on the body, or to heat it. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.
