Is it true that gravitational mass is equal to inertial mass?
Partly. Several sources state that gravitational and inertial mass are equal, some citing experimental confirmation, while others argue that active or passive gravitational mass differs from inertial mass except at rest. The items address narrower formulations rather than the general claim directly.
