The discussion revolves around the relationship between acceleration, mass, and gravitational effects, particularly whether gravitational acceleration can lead to mass increase similar to that caused by a driving force. The conversation touches on concepts from relativity and specific experimental evidence related to energy changes in gravitational fields.
Participants express differing views on whether gravitational acceleration can lead to mass increase, with some asserting it does not while others explore the implications of energy gain without mass conversion. The discussion remains unresolved with multiple competing perspectives.
There are limitations regarding the assumptions made about mass-energy equivalence and the specific conditions under which gravitational effects are considered. The relationship between energy gain and mass conversion is not fully explored, leaving open questions about the nature of energy in gravitational fields.
Could you be thinking about the Pound and Rebka Mossbauer Effect experiment at Harvard in which photons from an iron-57 source falling from the roof to the basement of the phyics building gained a measurable amount of energy? In this case there was no mass gained, but the photon energy gain was due to gravity.tanzanos said:If an object increases mass with acceleration due to the energy driving force converting to mass then is it true also when there is no driving force but gravitational tug acting to accelerate the object?
So gravitational tug causes an object to gain energy but that energy does not convert to mass? What happens to this energy?Bob S said:Could you be thinking about the Pound and Rebka Mossbauer Effect experiment at Harvard in which photons from an iron-57 source falling from the roof to the basement of the phyics building gained a measurable amount of energy?

For photons, E2=(pc)2 + (m0c2)2, so for photons with zero rest mass, the energy increase is equal to the momentum increase; E = pc.tanzanos said:So gravitational tug causes an object to gain energy but that energy does not convert to mass? What happens to this energy?
