This entry relates to the physical concept of speed; for the film, see Speed (1994 film)

Speed is the rate of motion, or equivalently the rate of change in position, often expressed as distance d traveled per unit of time t.


  • Be wise with speed;
    A fool at forty is a fool indeed.
  • Ease and speed in doing a thing do not give the work lasting solidity or exactness of beauty.
  • Speed has never killed anyone. Suddenly becoming stationary, that's what gets you.
