Energy Conversion in Lifting Mass Vertically using a DC Electric Motor by Observing Required Time to Lift Object for a Certain Height
arXiv:1408.5111
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 Δt 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.
