Mechanical Energy

on . Posted in Classical Mechanics

energy PE KE MEMechanical energy, abbreviated as ME, is the sum of the change in kinetic energy and potential energy generating from the force of gravity, external forces or the movement released in machine movement.  The principle of conservation of mechanical energy states that in an isolated system that is only subject to conservative forces, the mechanical energy is constant.


Mechanical energy formula

\(\large{ ME =  PE + KE }\)
Symbol English Metric
\(\large{ ME }\) = mechanical energy \(\large{ lbf-ft }\) \(\large{J}\)
\(\large{ KE }\) = kinetic energy \(\large{ lbf-ft }\) \(\large{J}\)
\(\large{ PE }\) = potential energy \(\large{ lbf-ft }\) \(\large{J}\)
