## ac·cel·er·a·tion

(ăk-sĕl′ə-rā′shən)
The rate of change of the speed or direction of a moving body with respect to time. See more at gravity, relativity.
Did You Know? Most people know that an object has weight because of the pull of gravity, but did you know that weight is actually an indication that an object is being accelerated? When you're in an elevator, for example, as the elevator accelerates upward or downward you feel as if your weight is changing—you feel heavier when the elevator is accelerating upward, and lighter as it accelerates downward. Stand on a bathroom scale in the elevator, and you'll see that the effect is real: the readout on the scale does indeed change as the elevator accelerates. When it accelerates upward and you feel heavier, the readout increases; when it accelerates downward and you feel lighter, the readout decreases. Exactly what is changing as you move upward and downward in the elevator? It isn't your mass—the amount of matter in your body. That remains the same. Actually, it's your acceleration that is changing. Your speed and direction are changing, as the elevator moves faster or slower and goes up or down. So the changes in your weight shown on the scale actually are a measure of changes in your acceleration.

## acceleration

Rate of change in velocity, measured in feet (meters) per second per second (ft(m)/sec2).
