Question

What is free fall? Write the equations of motion for a body falling freely downwards.
​

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/s2  (Taking downward direction to be positive)

Initial speed of that body  u=0

Equations of motion :

(i) :  v=gt

(ii) :  S=21gt2

(iii) : v2=2gS

hope this much helps uh ❣

Answer 2

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

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

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

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)
