Weight is not an intrinsic property of an object because:

1. Mass is the quantity of matter and does not vary in classical physics. 2. Weight is the gravitational force and does vary depending on gravity. 3. The acceleration due to gravity varies slightly over the surface of Earth. 4. So the weight of an object depends on location and is not an intrinsic property of the object. 5. On the Moon the acceleration due to gravity is smaller still, so the same object weighs less. _Source: OpenStax College Physics for AP(R) Courses 2e (CC BY 4.0), Ch 4 'Dynamics: Force and Newton's Laws of Motion', sections 4.1-4.8_
