What if mass is not constant?When we use the formula L= mxvxr. We usually hold mass to be constant. For example when the Earth orbits the Sun the r which is the separation distance gets smaller so to compensate and for conservation of angular momentum to be true the velocity should increase but mass is supposed to be constant. Now we come to relativity. Suppose the earth orbits the sun at the speed of light. Then its mass should increase. Now when we keep r constant that means the distance between the sun and earth is the same when Earth orbits the Sun. Now mass has increased due to higher speed. But r is constant so since mass has increased the velocity is decreased. So is this another way of proving Relativity? |

I think I can pick out the gist of your argument, moving away from the impossible (earth at the speed of light) consider a smaller object, say a lead ion, being accelerated around a synchrotron ring. As the speed increases into relativistic realms, the increased relativistic mass should be noticeable in the increased magnetic energy required to steer the ion around the ring. The energy needed to hold the radius constant will not match the Newtonian equations. |

The correct expression is L = r x pwhere p = mv. In this expression m is a function of v.Regarding So is this another way of proving Relativity? - No. Relativity cannot be proved. No scientific theory can be proved. |
