v=u+at This is the equation of motion for linearly moving objects.
In above equation of motion
v=final velocity
u=initial velocity
t=time
a=acceleration
a is linear acceleration and for a freely falling body this linear acceleration is equal to gravitational acceleration g so the equation of motion for free fall body will be
v=u+gt

Free Fall:
A body is said to be free fall when only gravitational force acts on that body.
General equation of motion:
1. V=u+at
Important Points to Remember:
-->When a body is falling vertically downwards its velocity increases.
So g=+g =+9.8m/s²
--->For a free fall object:
initial velocity =u=0;
equation of motion will change as
V=0+gt ⇒v=gt
