The Proof for NEWTON'S Third Equation of Motion
Newton gave 3 equations for motion
1. v = u+at
2. s = ut+ 1/2 at²
3. v² = u²+2as
This is a proof for Newton's second equation of Equation s= ut+1/2 at²

Let, s = displacement
t = time
V = average velocity between two points
u = initial velocity
v = final velocity
a = acceleration,
a = (v-u)
t
Average velocity × a = Average velocity × (v-u)
t
s × a = (v+u) × (v-u)
t 2 t
s × a = (v+u)(v-u)
t 2t
s × a = v²-u²
t 2t
2 × t × s × a = v² - u²
t
2as = v² - u²
u² + 2as = v²
v² = u² + 2as
