Question

find an expression for a freely falling body​

Answer 1

Answer:

A freely falling body always experience a downward acceleration g which we call as acceleration due to gravity.

Thus acceleration of freely falling body a=g=9.8 m/s

2

(Taking downward direction to be positive)

Initial speed of that body u=0

Equations of motion :

(i) : v=gt

(ii) : S=
