Question

what is acceleration......???​

Answer 1

Answer:

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Answer 2

Answer:-

The rate of change of velocity of an object with respect to time is known as acceleration.

Acceleration = change in velocity /time taken

Eg : Falling of an apple from its tree

About acceleration

Acceleration is a vector quantity

It's SI unit is meter per second square.

Formula of acceleration is

$\boxed{a \: = \frac{v \: - \: u}{t} } </p><p>a= </p><p>t</p><p>v−u</p><p>$

Where a = acceleration

v = final velocity

u = initial velocity

t = time
