WebApr 8, 2024 · If the gravitational energy is GMm/r, then kinetic energy is GMm/2r and this kinetic energy is positive. When kinetic energy and the potential energy are added up, the total will come out to be the gravitational potential energy, given by, T.E. = - GMm/2r = 1/2 P.E. or 1/2 (- GMm/r) WebThis is the general expression for gravitational potential energy. It obviously depends on the point of reference. Now, if the two objects in the system are closer together than the zero configuration which is the reference point r f , r will be smaller than r f . WebOct 7, 2003 · 0. A protostar will begin gravitational collapse only if the total gravitational potential energy exceeds twice the thermal energy. In other words, a gas has to be sufficiently cool and sufficiently dense to collapse. Also, as the protostar collapses about half of the gravitational PE is converted into heat, and about half is radiated into space. breaker wiring for 220 line in box
