Question

what is acceleration​

Answer 1

$\huge\mathcal\purple{Answer}$

The rate of change of velocity is called acceleration.

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

S.I unit of acceleration is m/s²

Answer 2

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
