Question

state and prove three equation of motion graphically​

Answer 1

Answer:

Three equation of motion are

• v=u +at
• s= ut + 1 at²

2

• v² - u² = 2as

Explanation:

prove first equation

v = u + at

proving

acceleration =v-u

t

i.e. a= v-u

t

at = v- u

at + u = v

v = u+at

proving equation s= ut + 1 at²

2

v+u. = s

2. t

( v + u is the distance)

u + at + u = s (value of v is

2 t u+at )

by cross multiply

2u+at² = 2s

cancelling 2

s = ut + 1 at²
