Question

define acceleration ????​

Answer 1

Answer:

Change in velocity in per unit time is termed as Acceleration. SI unit is m/s^2

Formula = v-u/t

Answer 2

Answer:

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.

Explanation:

Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing. For all other kinds of motion, both effects contribute to the acceleration.
