In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Acceleration is one of several components of kinematics, the study of motion.

Dec 5, 2025 · Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down.

The meaning of ACCELERATION is the act or process of moving faster or happening more quickly : the act or process of accelerating. How to use acceleration in a sentence.

Acceleration is the rate of change of velocity with time. An object accelerates whenever it speeds up, slows down, or changes direction.
