If I lift 40 kg 6 times 60 centimeters, is that 40*6*0,6*9,82 Joule? And then if I take the time into account, I will know the Watts? Or did I misunderstand?
The background is that I read that you can use the work from exercising to power energy, and I find that one set that I do is 50 Watts approximately. So if I theoretically could find a way to use the work I do, that would be 50 Watt?
