Please look into this site http://knol.google.com/k/alex-belov/paradox-of-classical-mechanics-2/1xmqm1l0s4ys/9# The experiment 2 animations This is animation based on classical mechnics laws http://mysite.verizon.net/vze27vxm/sim.gif This is animation based on theory of standalone rotation with translation movement. http://mysite.verizon.net/vze27vxm/movie2.gif The Natural Experiment 2. I made 3 successful experiments with 2 pencils. On all these experiments pencils with rotation movement have lower velocity than pencils without rotation. The theory is CORRECT. The simulator is WRONG. Materilas: 2 pencils and thin rubberband 3.5'' from Staples store. The rubberband is repulsing 2 objects(2 pencils). Two their parts have opposite velocities to each other. After initial action the rubberband has velocity zero. The rubberband mass much less then pencil mass. Here is some snapshots which shows experiment dynamic. http://knol.google.com/k/-/-/1xmqm1l0s4ys/h6o9ht/1%20(1).jpg [Broken] http://knol.google.com/k/-/-/1xmqm1l0s4ys/h6o9ht/2%20(1).jpg [Broken] http://knol.google.com/k/-/-/1xmqm1l0s4ys/h6o9ht/3%20(1).jpg [Broken] http://knol.google.com/k/-/-/1xmqm1l0s4ys/h6o9ht/4%20(1).jpg [Broken] The rotation with translation movement is standalone natural phenomenon. It should have it's own law of momentum conservation.
