Impetus vs. Momentum — What's the Difference?

An impelling force; an impulse.

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

The force or energy associated with a moving body.

Symbol p(Physics) A quantity used to measure the motion of a body, equal to the product of the body's mass and its velocity. Also called linear momentum.

Something that incites; a stimulus.

The force or energy exhibited by a moving body

Increased activity in response to a stimulus

The driving force or advancing strength of a development or course of events

Anything that impels; a stimulating factor.

(Philosophy) An essential or constituent element; a moment.

A force, either internal or external, that impels; an impulse.

(physics) Of a body in motion: the tendency of a body to maintain its inertial motion; the product of its mass and velocity, or the vector sum of the products of its masses and velocities.

The force or energy associated with a moving body; a stimulus.

The impetus, either of a body in motion, or of an idea or course of events; a moment.

A principle of motive force, held as exquivalent to weight times velocity by John Buridan, in an auxiliary theory of Aristotelian dynamics introduced by John Philoponus, describing projectile motion against gravity as linear until it transitions to a vertical drop and the intellectual precursor to the concepts of inertia, momentum and acceleration in classical mechanics.

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

An activity in response to a stimulus.

Essential element, or constituent element.

A property possessed by a moving body in virtue of its weight and its motion; the force with which any body is driven or impelled; momentum.

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.

Fig.: Impulse; incentive; stimulus; vigor; force; as, the President's strong recommendation provided the impetus needed to pass the campaign reform bill.

An impelling force or strength;

The altitude through which a heavy body must fall to acquire a velocity equal to that with which a ball is discharged from a piece.

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

A force that moves something along

The act of applying force suddenly;
