What is power? (article) | Work and energy | Khan Academy
1. power is all about converting whatever your work into the work with 1 second of window. 2. in most cases, you do work for more than 1 sec. thus you have to do divide them by the time it take to do the work. e.g. work_of_pushing_a_box_right = 30J, time = 3s. power = work/time = 30J/3s = 10J/1s = 10W.
How to calculate battery energy – x-engineer
