1.v=u+at
let to a body move initial velocity u if accleration a in time t the final velocity
change in velocity
acceleration= --------------------------
time taken
v-u
a= --------
t
at=v-u
at+u=v
v=u+at
proved.........
2.s=ut+1/2at²
let to a body move initial velocity u it acceleration a in time t then find final velocity becomes and travell distance s.
initial velocity+final velocity
a.v= -----------------------------------------
2
u+v
a.v= -----------
2
distance travell by body=average velocity *time
(u+v)t
s= ---------
2
(u+u+at)t
s= --------------- {∴v=u+at}
2
(2u+at)t
s= ------------
2
s= (2u/2+at/2)
s= ut+1/2at²
proved.............
3.v²=u²+2as
let a body move with initial velocity u and uniform acceleration a. after travelling a distance s its velocity become v
distance traveled =av.velocity*time
v+u+t
s= ------------
2
v+u v-u
s= ------ * ------
2 a
(v+u)(v-u)
a= -------------
2a
2as=v²+u²
⇒v²+u²=2as
