Gravity

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
\(\large{ g = \frac {PE} {m \; h}  }\)
Symbol	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	\(\large{ ft-lbf }\)	\(\large{ J }\)
