Question

$\sf$ what is meaning of acceleration ??​

Answer 1

Answer:

The definition of acceleration is a change in the rate of motion, speed or action. An example of acceleration is increasing your driving speed from 45 to 55 to merge with traffic.

Answer 2

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. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
