Answer
Mass is a constant unit to measure the quantity of a matter while weight is the heaviness of that quantity under certain circumstances.
Work Step by Step
Mass of anything does not change under different gravity but the weight of the object changes at different gravity. Where mass is the actual quantity of any object, weight refers to the heaviness of the object. Weight can be more than mass or less. It changes from place to place.
For Example:A person whose weight on Earth is measured at 60 kg will be only about 10 kg on the moon. The reason behind this is the low gravitational force on the moon which make the body lighter. Mass is the subject matter contained in anobject.
