Does something moving fast weight less? Would it get less G if it would spin really fast ? Or does speed only affect "speed of time" ?

- dogma1138 6y agoAs objects move faster their (relativistic) mass increases*, the invariant mass however doesn’t change. *Relative to an external observer.
- Zamicol 6y agoAre there any experimental tests of relativistic mass?
- fsh 6y agoYes, any particle accelerator has to account for the relativistic mass in order to function.
- dogma1138 6y agoYes, and pretty old ones at that https://en.wikipedia.org/wiki/Kaufmann%E2%80%93Bucherer%E2%80%93Neumann_experiments https://en.wikipedia.org/wiki/Kaufmann%E2%80%93Bucherer%E2%8... Special relativity is weird, but it's very much proven by countless experiments. https://en.wikipedia.org/wiki/Tests_of_special_relativity https://en.wikipedia.org/wiki/Tests_of_special_relativity
- elihu 6y agoMy understanding which could be wrong is that the kinetic energy of an object can itself cause (tiny amounts) of gravity. So, for instance, a spinning object would weigh slightly more.
