Given an parachuter and the system parachuter-parachute-Earth and taking in account the resistance of the air, my question is: is the mechanical energy of the system (parachuter.parachute.Earth) a constant, please explain. And please don't talk just about the parachuter because I wan't to know about the parachuter and Earth as one system.
Thank you in advance.
