Acceleration vs. Momentum

Accelerationnoun

(uncountable) The act of accelerating, or the state of being accelerated; increase of motion or action; as opposed to retardation or deceleration.

Accelerationnoun

(countable) The amount by which a speed or velocity increases (and so a scalar quantity or a vector quantity).

Accelerationnoun

(physics) The change of velocity with respect to time (can include deceleration or changing direction).

Accelerationnoun

The advancement of students at a rate that places them ahead of where they would be in the regular school curriculum.

Accelerationnoun

The act of accelerating, or the state of being accelerated; increase of motion or action; as, a falling body moves toward the earth with an acceleration of velocity; - opposed to retardation.

Accelerationnoun

an increase in speed;

Accelerationnoun

the act of accelerating; increasing the speed

Accelerationnoun

(physics) a rate of change of velocity

Acceleration

In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction).

Momentumnoun

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

Momentumnoun

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

Momentumnoun

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

Momentumnoun

Essential element, or constituent element.

Momentumnoun

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.

Momentumnoun

an impelling force or strength;

Momentumnoun

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

Momentum

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