What's the difference between inertia and momentum?

Inertia


Definition:

  • (n.) That property of matter by which it tends when at rest to remain so, and when in motion to continue in motion, and in the same straight line or direction, unless acted on by some external force; -- sometimes called vis inertiae.
  • (n.) Inertness; indisposition to motion, exertion, or action; want of energy; sluggishness.
  • (n.) Want of activity; sluggishness; -- said especially of the uterus, when, in labor, its contractions have nearly or wholly ceased.

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.
