In order to calculate the potential energy of an object pe multiply the object s mass in kilograms m by the earth s gravitational constant g and the height of the object from the floor in meters h. The basic unit of energy and work is the joule j. Ke m v 2.

In spectroscopy the unit cm 1 0 0001239 ev is used to represent energy since energy is inversely proportional to wavelength from the equation e h nu h c lambda. The basic potential energy formula pe mgh is most commonly used in a straightforward manner. Spring force fs this force is equal to the spring constant for a given spring multiplied by the displacement the spring is stretched from the equilibrium position. At 1 m above the ground it s potential energy is.
