# Gravity

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Gravity, abbreviated as g, also called gravitation, is a force pulling togeather all matter.  Everything that has mass has a gavitational pull that is exerted on one another.  The larger the mass, the stronger the gravitational pull is exerted, this includes all matter.

## Gravity formula

 $$\large{ g = \frac {PE} {m \; h} }$$

### Where:

 Units English Metric $$\large{ g }$$ = gravity $$\large{\frac{ft}{sec^2}}$$ $$\large{\frac{m}{s^2}}$$ $$\large{ h }$$ = height $$\large{ ft }$$ $$\large{ m }$$ $$\large{ m }$$ = mass $$\large{ lbm }$$ $$\large{ kg }$$ $$\large{ PE }$$ = potential energy $$\large{ ft-lbf }$$ $$\large{ J }$$
