What's the difference between impulse and pulse?

Impulse


Definition:

  • (n.) The act of impelling, or driving onward with sudden force; impulsion; especially, force so communicated as to produced motion suddenly, or immediately.
  • (n.) The effect of an impelling force; motion produced by a sudden or momentary force.
  • (n.) The action of a force during a very small interval of time; the effect of such action; as, the impulse of a sudden blow upon a hard elastic body.
  • (n.) A mental force which simply and directly urges to action; hasty inclination; sudden motive; momentary or transient influence of appetite or passion; propension; incitement; as, a man of good impulses; passion often gives a violent impulse to the will.
  • (v. t.) To impel; to incite.

Pulse


Definition:

  • (n.) Leguminous plants, or their seeds, as beans, pease, etc.
  • (n.) The beating or throbbing of the heart or blood vessels, especially of the arteries.
  • (n.) Any measured or regular beat; any short, quick motion, regularly repeated, as of a medium in the transmission of light, sound, etc.; oscillation; vibration; pulsation; impulse; beat; movement.
  • (v. i.) To beat, as the arteries; to move in pulses or beats; to pulsate; to throb.
