The equation underlying general relativity, also called Einstein's field equation, is based on the equivalence principle, which establishes that inertial mass and gravitational mass are equivalent. However, the respective definitions of the two types of mass are different: the inertial mass is proportional to the inertia of a body, which is the resistance to the change of the state of motion when a force is applied, while the gravitational mass is proportional to the interaction force. of a body with gravitational force.
Do you know how gravity affects time?
The equivalence principle is so-called because an observer jointed with the moving masses is unable to distinguish an acceleration due to an external force from that produced by a gravitational field. The difference is visible only from a reference system that is not jointed with the moving masses.
To try to better understand this principle, Einstein himself proposed the elevator thought experiment.
