Question

Consider the equation and rewrite from a free fall body v=u+at s=ut+1/2at

Answer 1

in free fall body

a = acceleration due to gravity . but in negative sign ( because this is directed in downward direction )

u = zero

we choose Reference level at highest point , and body moves downward so,

V is also negative

v = u + at

-v = 0 - gt

-v = -gt

v = g

Answer 2

it is a question from physics, my friend!!!!
