Question

Derivation of first equation of motion

Answer 1

We have a=v-u/t
at=v-u
at+u=v
v=u+at

Answer 2

First equation of motion:-

v = u + at

Where,

v = Final velocity,

u = Initial velocity,

a = Acceleration,

t = Time.

Derivation:-

Acceleration = Change in Velocity / Time taken

a = (v - u) / t

v - u = at

v = u + at (Proved).
