What's the difference between momentum and velocity?

Momentum


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.

Velocity


Definition:

  • (n.) Quickness of motion; swiftness; speed; celerity; rapidity; as, the velocity of wind; the velocity of a planet or comet in its orbit or course; the velocity of a cannon ball; the velocity of light.
  • (n.) Rate of motion; the relation of motion to time, measured by the number of units of space passed over by a moving body or point in a unit of time, usually the number of feet passed over in a second. See the Note under Speed.
