    I am fairly new to electromechanical devices, therefore I would like someone to aid me with my computation. Suppose that I wanted to propel a load with an electric motor forward, much the way a "hoverboard" or an electric skateboard does. How would I go about performing the calculations to determine the motor I need? Things I suppose I'd have to factor in are weight (motor, load, and batteries), speed at which I want to travel as well as battery lifetime.

    You will also need to factor in any forces you need to overcome, such as wheel rolling friction, gravitational force (going up hill), bearing friction, wind, and make allowances for inefficiency of the motor and battery charging/discharging.
