# Free Fall

Written by Jerry Ratzlaff on . Posted in Relativity

Free fall means falling freely with no forces acting upon it except gravity.

## Free Fall formula

 $$\large{ s = \frac{1}{2} \; g \; t^2 }$$

### Where:

 Units English Metric $$\large{ s }$$ = free fall (speed) $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$ $$\large{ g }$$ = gravity $$\large{\frac{ft}{sec^2}}$$ $$\large{\frac{m}{s^2}}$$ $$\large{ t }$$ = time $$\large{sec}$$ $$\large{s}$$
