Question

how will the three equations of uniformly accelerated motion of a body change if body starts from rest

Answer 1

Hey!

_______________________________

Three equations of motion are as follows-

• v-u= at
• v^2-u^2= 2as
• s= 1/2 at^2+ut


If body starts from rest, then, u=0
If this is the case, then equation of motion will be changed as follows-

• v-u=at

v-0=at
v=at

• v^2-u^2=2as

v^2-0=2as
v^2= 2as

• s= 1/2at^2+ut

s= 1/2at^2+ 0×t
s=1/2at^2
