Accelerationnoun

(uncountable) The act of accelerating, or the state of being accelerated; increase of motion or action; as opposed to retardation or deceleration.

Accelerationnoun

(countable) The amount by which a speed or velocity increases (and so a scalar quantity or a vector quantity).

Accelerationnoun

(physics) The change of velocity with respect to time (can include deceleration or changing direction).

Accelerationnoun

an increase in speed;

Accelerationnoun

the act of accelerating; increasing the speed

Accelerationnoun

(physics) a rate of change of velocity

Acceleration

In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction).

Decelerationnoun

(uncountable) The act or process of decelerating.

Decelerationnoun

(countable) The amount by which a speed or velocity decreases (and so a scalar quantity or a vector quantity).

Decelerationnoun

a decrease in velocity. Opposite of acceleration

Decelerationnoun
