Question

Write the equations of motions for (1) free fall​

Answer 1

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

Answer 2

Answer:

.The formula for free fall:

Imagine an object body is falling freely for time t seconds, with final velocity v, from a height h, due to gravity g. It will follow the following equations of motion as: h= 1 2 g t 2 \frac{1}{2}gt^2 21gt2. v²= 2gh. v=gt.
