It is lovely simplicity like this that occasionally makes me want to live a life of not really giving a fuck.

I've got a question. I'm learning about physics (senior in high school) and something we just covered was the idea of forces.

How did newton (or who ever, it's hard to keep track of all the historical figures who said all these different things) find that objects that are moving only stop because of friction, and if they were moving with no other forces acting on them (say, in space), they'd keep going forever?

that seems to me like that'd be an experiment you could only learn from if you were able to compare it, and by that i mean go into space and see it happen. was he just looking for 'the piece that connected the parts' and made up the idea of friction, which happened to do just that?

I realize a lot of this is open to exception or misinterpretation so I apologize, I hope you guys see where I'm coming from. thank you

or angular momentum
we should talk about this
basically this man claims the machine can keep running and not only generate power but create and excess of power for homes and such

tl;dr machine is perpetual motion kinda
