First equation of motionwe know that

a=change in velocity /time

a= v-u/t

at=v-u

So, v=u+at.

Second equation of motionWe know that

Distance = av. velocity * time

S=(u+v/2)*t ———1

And v=u+at ————2

Equating both equations

S=1/2(2ut+at² )

So, S=ut +1/2at²

Third equation of motionAs we know

V=u+at

Squaring both side

V² = (u+at)²

V²=u²+a²t²+2uat

V²=u²+2a(1/2at²+ut)

V²=u²+2as

V²-u² = 2as.

These are the proof of equations of motion

First equation of motionwe know that

a=change in velocity /time

a= v-u/t

at=v-u

So, v=u+at.

We know that

Distance = av. velocity * time

S=(u+v/2)*t ———1

And v=u+at ————2

Equating both equations

S=1/2(2ut+at square )

So, S=ut +1/2at2

Third equation of motionAs we know

V=u+at

Squaring both side

V2=(u+at)2

V2=u2+a2t2+2uat

V2=u2+2a(1/2at2+ut)

V2=u2+2as.

These are the proof of equations of motion
