Answer 2

$\huge \mathcal { \blue{ \boxed{Answer}}}$

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

$\boxed{a \: = \frac{v \: - \: u}{t} }$

Where a = acceleration

v = final velocity

u = initial velocity

t = time
