Final answer:
Mass is an intrinsic property of an object and does not change with location or gravitational force, while weight is the force due to gravity acting on an object and varies depending on gravitational force.
Step-by-step explanation:
The relationship between weight and mass is that weight is the force due to gravity acting on an object, while mass is an intrinsic property of the object and does not change with location or gravitational force.
For example, a 70-kg astronaut in space, far from any celestial body, would have a weight of zero because there is no gravitational force acting on her. However, her mass would still be 70 kg.
