v=u+at
for freely falling body u is zero
so v=gt as gravity is acting
for freely falling body u is zero
so v=gt as gravity is acting
is this a correct answer
i think
ok
direction of velocity is downwards

for a free fall body ,
a = -g { g is acceleration due to gravity which is always directed in downward direction so, negative sign include here .
because we choose reference point of . highest level so,
v = -ve
then,
-V = u -gt
but in free falling initial velocity =0
so, -V = 0 -gt
-V = -gt
V =gt
a = -g { g is acceleration due to gravity which is always directed in downward direction so, negative sign include here .
because we choose reference point of . highest level so,
v = -ve
then,
-V = u -gt
but in free falling initial velocity =0
so, -V = 0 -gt
-V = -gt
V =gt
is this correct
100% perfect . if you want to explanation read some advance book of physics
@prema mam my sir asked g is always taking negative , but conside woth refference level
you have to say that direction of velocity is downwards.. v = g t. or if reference direction is upwards, then v = - g t
