let an object is having initial velocity u and final velocity v and object is moving with a uniform acceleration a and a is the displacement. then ,
v2- u2 = 2as
s = v2- u2/ 2as
W= FS
=ma x v2-u2/2as
= 1/2 (mv2-mu2 )
if u= 0
KE or W = 1/2 mv2
v2- u2 = 2as
s = v2- u2/ 2as
W= FS
=ma x v2-u2/2as
= 1/2 (mv2-mu2 )
if u= 0
KE or W = 1/2 mv2
