Video: electric motors & generators: converting between electrical and mechanical energy both generators and electric motors are common devices in everyday life, but how do they work and what is the difference between them in this lesson, we'll explore both of them, which may produce different results but are actually. Conservation of energy- video analysis (4/10/2018) (approx 60 min) introduction the work-energy theorem tells us that changes in kinetic energy, k = ½ mv2 , are caused by work done by forces a special case pertains when conservative forces do work on objects a conservative force is one for which the work. To address this issue, nanoscale fillers, such as carbon nanotubes (cnts), have been utilized to dissipate mechanical energy in polymer-based samples were subjected to dynamic mechanical analysis, and the damping of the samples were measured as the ratio of the loss to storage moduli versus.
Part of total output energy of the power source has to overcome some energy consumptions caused by the rolling resistance, the air resistance, and the slope of the road resistance, thus the remaining energy is converted to vehicle kinetic energy.
