Hello, I thought of asking would someone know what is the correct thinking here... A body is thrown upwards, its kinetic energy gradually transforms into gravitational potential energy until it is entirely absorbed. At this moment, where is the potential energy? According to wikipedia (N. Umov) "Umov considered potential energy as kinetic energy of some environments "imperceptible for us". From this hypothesis, he made a conclusion: it is always possible to specify a place where the energy is in." Perhaps general relativity gives the answer... Sadly, I hardly know anything about GR Thanks in advance.
