Yep smile
But no, not perpetual motion. A little convenient that there's a hidden bit in the middle which keeps it all running, isn't it?

Just think. If the ball is being pulled towards the magnet, then pulling the magnet away from the ball takes at least as much energy...

Which, correct me if I'm wrong, is imparted by the pendulum system????

oh fkit we're going to be back at planes and conveyour belts in a minute.

OP- do you beleive you can saw a woman in half even thought you've seen a magician do it?

no?

Correct me if I am wrong (as I am very likely to be) but I was always taught that a perpetual motion machine would need to ability to covert energy into movement and back to energy again with 100% efficiency. In this case the movement of the ball would be suffering from friction loss via the air and the rails, even if those loses are very small in terms of % lost, its still a loss and would eventually run out of energy and therefore not be perpetual motion.

Perpetual motion it isn't it might be seriously efficient so the first nudge gives it enough energy to run for long enough the average observer gets bored and wanders off before it stops moving, but it will stop, as it is always loosing energy to something.

Which is not perpetual (and the panel will fail long before that).




teacher Perpetual does not mean 'for quite a long time' - it means FOR EVER.

Yeah but what about if you attached a greased magnet to a spring-loaded waterwheel at absolute zero in a vacuum and don't be an imbecile of course there's no such thing as a perpetual motion machine.

At the risk of ridicule, a serious question if I may? Is the Universe as a whole a perpetual motion machine? A closed system with a fixed amount of energy within?

No

one of two things will happen- either all the entropy will be evenly distributed, in which case everything stops. or it massively contracts, in which case everything ends.

whatever happens, its not going to be perpetual.

At least thats what current physics shows us.

Yeah, I know, I was just trying to add to the story being generated. Perpetual motion is not possible based on physics as we know it!
