Abstract

In lifting mass vertically using a DC electric motor energy conversion from electric energy, through intermediate kinetic energy, to gravitation potential energy shows that time required {\Delta}t to lift load mass m for height h is dependent quadratically to m. Several approaches to explain the experiment observation are discussed in this work, from ideal energy conversion to numerical solution from differential equation.
