Question

define acceleration?

Answer 1

acceleration is the rate of change of velocity in time.

formula of acceleration :

(v-u)/t

where ,

u is the initial velocity

v is the final velocity

t is the time

please mark me as brainliest

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.

Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.

$acceleration = \frac{change \: in \: velocity}{time}$
