Question

what is acceleration?prove that a= v-u÷t​

Answer 1

Explanation:

Acceleration :-

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

It is a vector quantity.

__________________________________________________________

$Prove \: that : \: \: a \: = \: \frac{v - u}{t} \\ \\ we \: know \: that \: acceleration \: (a) \: = \: rate \: of \: change \: of \: velocity \\ \\ \implies \: a \: = \frac{change \: in \: velocity}{time \: taken} \\ \\ \implies \: a \: = \: \: \frac{final \: velocity \: - \: initial \: veloity}{time \: taken} \\ \\ \implies \: a \: = \: \frac{v \: - \: u}{t}$

Hence proved .
