How is weight defined?

Weight is fundamentally defined as the measure of the gravitational force exerted on an object. It is influenced by both the mass of the object and the gravitational acceleration acting on it, which varies depending on the location (for example, weight will differ on the Moon compared to Earth due to the difference in gravitational pull). While mass reflects the amount of matter in an object and is constant regardless of location, weight varies based on the gravitational field strength. As such, the correct interpretation focuses on the interaction between an object's mass and the gravitational force acting upon it, which defines its weight. This distinction highlights the relational aspect of weight compared to other physical properties like volume or density, which do not account for gravitational influence.
