Question

derive first equation of motion class 9 physics. please tell me answer fastly by drawing please ​. understand my situation

Answer 1

Derivation:-

For the derivation you must know that acceleration can be written as ratio of ∆V and time here ∆V is change in Velocity.

So we can write acceleration as

$\large \rightarrow \: a = \frac{∆V}{t}$

Also we know that

$\large \rightarrow \:∆V = v - u$

here v is final velocity and u is initial velocity

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

$\large \rightarrow \: a \times t = {v - u}$

$\large \rightarrow \: at + u = v$
