Nominal values are the average values obtained after testing a sample population of the motor model. - Nameplate Work, Energy and Power: Problem Set Overview This set of 32 problems targets your ability to use equations related to work and power, to calculate the kinetic, potential and total mechanical energy, and to use the work-energy relationship in order to determine the final speed, stopping distance or final height of an object.
