Why are inertial and gravitational mass equal in Newtonian physics? the fact that Newtonian theory gives no reason to expect these two masses to be related. question takes the Newtonian concepts of gravitational and inertial mass for granted. Given that gravitational mass does not make sense in GR, one might say that the question turns out to be To answer the question, one needs to show, in detail, how Newtonian theory relates to case of GR, are inertial and gravitational mass equal in Newtonian theory? classical spacetime needs to satisfy in order to recover standard Newtonian theory, which are not trivial. 23A classical spacetime as considered by geometrized Newtonian theory is generally curved, though space A.3 Gravitational Mass in Newtonian Theory particle's coupling to the gravitational field is given by its inertial mass. gravitational field is given by its inertial mass.	./cache/work_njzwjkxyrzh4rbhhlj6ccr6kwm.pdf	./txt/work_njzwjkxyrzh4rbhhlj6ccr6kwm.txt
