Big try at gravity wheel

Marsing, it is very difficult sometimes to parse your English.  If Grimer is onto something then I think that accelerating proving that is a good idea.  That can only be done if Grimer says what his idea is.

So far as I can presently tell, he is arguing that the amount of gravitational energy change between two heights depends on the path taken between those points.  We can easily construct experiments with pendula or marbles rolling on smooth 'U' shaped tracks with different slopes that dispute such an idea.  Those types of experiments won't help if Grimer is right.  What I need from Grimer is statement of some special limitation that has not been previously tested and shown to act conservatively.  Then we can design an experiment that if it does show a difference in energy will disprove that gravity is conservative.

The amount of gravitational energy in the drop is the same. It's the amount of Ersatz that's different. The dancer is doing more work pulling her arms in.


CAN'T YOU SEE THAT!!!!

Grimer do we agree on my bullet points 3) and 4):

3) The swing height change Hdelta on the right in Quadrant IV is the same as the swing height in Quadrant III.  The change in PE is the same.
4) The velocity magnitude at the bottom of the swing going from Quadrant III to Quadrant IV is identical to that going from Quadrant IV to Quadrant III.  The KE peak magnitudes are the same.

Work is the dot product of displacement against force.  Displacement normal to force does no work.

You can stick your bullet points where the sun don't shine.




I asked a question. Answer it.

some will think different
