Thank you so much nasu, I was way off! haha That's interesting, but I assume it wouldn't heat the water much, even if it were repeated many times, right? Thanks ModusPwnd, I see what you're saying. So all in all, it's not possible to create much heat simply using falling objects (unless we're...

Thanks paisiello2! So I imagine the friction of the weight on the right heats that poll? Do you know the type of material used? And to what degree it can heat if repeated?

Hello! I am trying to think of ways to generate significant amounts of heat through the motion of a falling object? Let's say we have a heavy ball and a structure that enables it to fall from a height of 30m for instance, how would you go about creating heat? I suppose you would have to use...

Oh great, thanks for the quick reply! Puts my mind to ease :)

I watched a documentary recently about electricity generation, and I've been trying to figure out whether an example they provided is actually possible or not in theory. If a big wheel, much like a Ferris wheel, spins but slowly, very slowly (let's say 5 revolutions per minute), and you...

Ok I get it now. Thanks for the reply!

Great, thanks for the replies. And Rooted, awesome document you have there! So is the amount of current produced proportional to the size of the pipe and strength of the magnet? I'm guessing yes, right? Like if we plugged light bulbs to the copper pipe, the bigger the pipe and stronger the...

The title is pretty self-explanatory. I know the speed of the falling magnet is much slower in a copper pipe, but since the magnetic field moves, is there still some electricity generated in the process, even though the speed isn't great? Thanks!

Haha no it's not a school assignment, I'm a graduate student but not in physics or natural sciences at all, I'm just interested in physics and curious! Thanks for the replies

Ok great, thanks!

Oh sure, I know I wouldn't be able to produce extra energy, I'm just wondering if there is a way to capture the energy produced, independently of how the object would go back up. It's just a hypothetical question

Well imagine a ball that falls from a few meters high and lands on a blade from the wheel. With its weight, it would make the wheel turn, right ? Now it probably would not make it turn fast enough to produce electricity, even with a gear-transmission box. But I used the water mill (or any other...

What's the best way to capture the energy produced by a falling object, and then use that energy to produce electricity for example ? Like for instance, I've been thinking of a kind of water mill where it would be an object falling on the blades instead of water, therefore making the mill...

That's what I thought, thanks for the replies! (and the link to Wikipedia, Drakkith! It's helpful)

Would a big ball weighing 100kg with a diameter of 1 meter float in water? I guess my question is, no matter how heavy an object might be, as long as it is less dense than water, it will float no matter what, right? Like even if that ball were made of a thick layer of steel (a few inches), as...
