acceleration

/ ækˌsɛləˈreɪʃən /

noun

1. the act of accelerating or the state of being accelerated

2. a. the rate of increase of speed or the rate of change of velocity

3. a. the power to accelerate

acceleration

1. The rate of change of the velocity of a moving body. An increase in the magnitude of the velocity of a moving body (an increase in speed) is called a positive acceleration; a decrease in speed is called a negative acceleration. Acceleration, like velocity, is a vector quantity, so any change in the direction of a moving body is also an acceleration. A moving body that follows a curved path, even when its speed remains constant, is undergoing acceleration.

acceleration

1. A change in the velocity of an object.

The most familiar kind of acceleration is a change in the speed of an object. An object that stays at the same speed but changes direction, however, is also being accelerated. (See force.)
