Law of Conservation of Mechanical Energy

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Law of conservation of mechanical energy states the total mecanical energy in a system remains constant as long as the only force acting are conservative forces.

Law of conservation of mechanical energy formula

\(\large{ PE_i + KE_i = PE_f + KE_f }\)         


\(\large{ KE_f }\) = final kinetic energy

\(\large{ PE_f }\) = final potential energy

\(\large{ KE_i }\) = initial kinetic energy

\(\large{ PE_i }\) = initial potential energy
