Hi, my question is rather simple. Supose you can generate 10 000N, by any means, such as pedaling a bycicle. What calculations should you make to know how much electricity would 10 000 N of force will generate. -Assuming a generator efficiency of 100%, leaving friction aside, etc. An example would be, how much electricity will i produce by pulling a string attached to the rotor of the generator, and the total force that will exert during 1 hour will be 10,000 N? If you also please tell me how i can convert the result to kWh? I have a very basic understanding of physics, and if you think i would not be able to understand your answer at this stage, may you please tell me what prior reading i should make before asking this question, or if you may give me a very detailed answer to my question. By the way, this is an amazing forum, and all its participants are really making an effort to help others. Thank you to you all.
