<P> The introduction of Newton 's laws of motion and the development of Newton 's law of universal gravitation led to considerable further development of the concept of weight . Weight became fundamentally separate from mass . Mass was identified as a fundamental property of objects connected to their inertia , while weight became identified with the force of gravity on an object and therefore dependent on the context of the object . In particular , Newton considered weight to be relative to another object causing the gravitational pull , e.g. the weight of the Earth towards the Sun . </P>
