Question

what is formula of acceleration​

Answer 1

$\frac{final \: velocity - initial \: velocity}{time \: taken} = acceleration$

Acceleration is the rate of change in velocity with respect to time . There are two types of acceleration :

• Positive acceleration = denoted by a positive sign .
• Negative acceleration = Denoted by a negative sign.

A body is said to be in positive acceleration when the rate of change in velocity is increasing.

A body is said to be in negative acceleration or decelerating when the rate of change of velocity is decreasing.

Answer 2

$\overline{a} = \frac{v - v_0}{t} = \frac{\Delta v}{\Delta t}$
