Question

v=u+at write the equation in free fall body

Answer 1

IN THE CASE OF A FREE FALL BODY, THE ACCELERATION OF BODY BECOMES= ACCELERATION OF GRAVITY .SO THE EQUATION BECOMES v=u+gt

Answer 2

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
