Very informative video.

If you extend the track so it won't fly off when the magnet goes, will it continue endlessly? It launches the end ball further than when you start it, so when it comes back, it'll also launch the end ball further, right?

No, because the initial ball is a magnet and won't fly off on the rebound.

Ah. If you are interested, we explain it all on our website. Here's a link: demos.smu.ca/demos/e-n-m/48-magnetic-accelerator

Does it break the conservation of momentum?
@SMUPhysics 4 жыл бұрын
No. The force from the magnet needs to be taken into account but momentum is always conserved!

@@SMUPhysics give it a rest, if 2 magnets start at bottom then in the end there are 2 magnet. Where does the energy come from? The magnets would have to loose magnetic strength. And you and I know it takes thousands of years for this to happen and is not caused by using the magnet.
