Gravitational Force

Gravitational mass refers to the measure of an object's susceptibility to gravitational forces. It quantifies how strongly an object interacts with a gravitational field. In the context of Newtonian gravity, the force of gravity (F) acting on an object is given by the product of its gravitational mass (m) and the acceleration due to gravity (g), expressed as \(F = m \cdot g\). Gravitational mass is a key quantity in Newton's law of universal gravitation and determines the strength of the gravitational force between two objects.

The principle of equivalence in general relativity suggests that gravitational mass is equivalent to inertial mass, which is the measure of an object's resistance to changes in its state of motion. This equivalence implies that all objects, regardless of their mass, experience the same acceleration in a gravitational field, assuming no other forces are acting on them. This fundamental equality between inertial and gravitational mass is a cornerstone of general relativity.
