Potential energy or work is measured in joules named after James Prescott Joule an English mathematician whose work created the formula about energy and its transference. The formula for the energy of motion is KE 5 m v2 where KE is kinetic energy in joules m is mass in kilograms and v is velocity in meters per second squared. Potential energy is energy which results from position or configuration.
Newtons three laws of motion form the basis for classical physics.
Like all work and energy the unit of potential energy is the Joule J where 1 J 1 kgm 2 s 2. The formula of electric potential is the product of charge of a particle to the electric potential. PE m x g x h 6 x 98 x 20 Potential Energy. The unit of charge is the Coulomb C and the unit of electric potential is the Volt V which is equal to a Joule per Coulomb JC.
