Mechanische paradox

De naam zegt het al; het is een paradox.
Je ziet een kegel op een helling omhoog rollen. natuurkundig gezien kan dit helemaal niet. Toch is dit omhoog rollen niet in strijd met de natuurkunde, omdat het zwaartepunt van de kegel toch daalt. Zwaarte-energie wordt dus omgezet in kinetische energie (en natuurlijk warmte).

I see an object start higher and end up lower. It's called gravity, not a paradox...

Lets settle this once and for all. The rail is narrow at the start, while at the end widens for the loss of height at the end because the the roller stays exactly level with the camera, with this, the table is slightly off. There! Observe it yourself. Classic camera illusion.

Its Clearly not a paradox, its a Conical shape on each side, So as it goes from left to right the rails move farther apart, the conical shape then rolls from the inside towards its outside, seeming to defy gravity, but it truly isn't. Its simply keeping the same line: Proof? Look at the Edge of the cone, it never moves vertically, its simple physics, Cool idea but is limited to the length of the cone.

Q - W = dU still applies

Q input = Work done by the assembly = 0

formula reduces to : 0 + 0 = dU = (PE2 + KE2)-PE1

Initial potential energy = Final potential energy + Kinetic energy of the motion

that thing is trying to fall in the hole of the rail, is not lift. False paradox.

@slome815 actually, a paradox is something that seems, on the face of it, self-contradictory but may (upon further examination) be well-founded (though, this last bit isn't required). Just because something seems impossible (and isn't) doesn't make it a paradox. It seems impossible that I can touch the sun but if we build tehcnology that allows me to do this then it doesn't make it a paradox. Self-contradictory is the key.

@BerkleyJ No, it do not end up lower. It follows a straight line.

But the taper make it move.

Actually the parallel rails the double coned object is riding on starts close together at the bottom, and they get farther apart at the top. The angle on the double cone (ball looking thing) is greater than the angle on the parallel rails, so gravity takes the path of least resistance.
