Question

Prove first equation of motion​

Answer 1

Answer:

• Let us assume a body has initial velocity ' u ' and it is subjected to a uniform acceleration ' a ' so that the final velocity be ' v ' after a time interval ' t '. Acceleration is the rate of change of Velocity.Now , by the definition of acceleration , we have :

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

$\large{ \tt{ \dashrightarrow \: at = v - u}}$

$\large{ \tt{∴ \: v = u + at - - - \tt{ {1}^{st} EQUATION \: OF \: MOTION}}}$

• And we're done! ☂
