What's the difference between acceleration and momentum?

Acceleration


Definition:

  • (n.) 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.

Definition:

  • (n.) The quantity of motion in a moving body, being always proportioned to the quantity of matter multiplied into the velocity; impetus.
  • (n.) Essential element, or constituent element.
