# Free Fall Formula

Freefall as the term says, is a body falling freely because of the gravitational pull of our earth.

Imagine a body with velocity (v) is falling freely from a height (h) for time (t) seconds because of gravity (g).

Free Fall FormulasÂ are articulated as follows:

$h\,&space;=\,&space;\frac{1}{2}\,gt^{2}$
$v^{2}\,&space;=\,&space;2gh$
$v\,&space;=\,&space;gt$

Free fallÂ isÂ independentÂ ofÂ theÂ massÂ ofÂ theÂ body.Â ItÂ dependsÂ onlyÂ onÂ theÂ heightÂ andÂ theÂ durationÂ theÂ bodyÂ isÂ flungÂ for.

## Freefall Related Solved Examples

Underneath are given questions on free fall which may be useful for you.

ProblemÂ 1:Â CalculateÂ theÂ bodyÂ heightÂ ifÂ itÂ hasÂ aÂ massÂ ofÂ 2Â kgÂ andÂ afterÂ 7Â secondsÂ itÂ reachesÂ theÂ ground?

Given: Height h =?
Time t = 7s
We all are acquainted with the fact that free fall is independent of mass.

Hence, it is given as

$$\begin{array}{l}h = \frac{1}{2}gt^{2}\end{array}$$

h = 0.5Â Ã— 9.8Â Ã— (7)2

h = 240.1 m

ProblemÂ  2:Â The cotton falls after 3 s and iron falls after 5 s. Which is moving with higher velocity?
