Every year I try to help my students gain an introductory view to
relativity, I learn more. I hope you will help me once again.
A question in Giancolli asks: Is a compressed spring more massive than the
relaxed version of the spring.
I understand that Work has been done and there is no change of KE.
Classically we say there is now PE stored. But it seems that to conserve
energy in the relativistic sense that there would be added mass measured.
If so, I wonder if the same would be said of an elevated mass?
I am ready to learn!
Thanks
