Gravitaatiomassa

Gravitaatiomassa, often simply called mass, is a fundamental property of matter that determines the strength of its gravitational interaction. It is distinct from inertial mass, which measures an object's resistance to acceleration. However, according to the equivalence principle, these two types of mass are always equal for any object. Gravitational mass is the source of gravitational fields and also the entity that responds to these fields. Therefore, an object with more gravitational mass exerts a stronger gravitational pull on other objects and is also pulled more strongly by their gravitational fields. The concept of gravitational mass is central to Newton's law of universal gravitation, which describes the attractive force between any two objects with mass. The larger the masses and the closer they are, the stronger the gravitational force. Einstein's theory of general relativity provides a more comprehensive description of gravity, explaining it not as a force but as a curvature of spacetime caused by the presence of mass and energy. In this framework, gravitational mass is one of the primary factors contributing to this spacetime curvature. Its precise nature and origin remain subjects of ongoing scientific inquiry.
