This principle is demonstrated by pushing a stalled compact car on a level road and then by pushing a stalled full-size car on a level road. The compact car will move much more easily because it has less mass. Mass doesn't change with location. The mass of an object on the surface of Earth is the same as it is in a microgravity environment. Weight, on the other hand, can change with location.
Weight is the net gravitational force of attraction acting on the mass of an object.
An astronaut walking on the Moon weighs one-sixth as much as on Earth because the net gravitational force on Earth is six times greater. One of the misconceptions many people have about rockets is that they need an atmosphere to push against in order to work. Many years ago, Robert Goddard, the inventor of the liquid propellant rocket engine, was soundly criticized by a newspaper editorial writer because the writer shared this misconception. New York Times editorial, 1921. The author of the editorial clearly did not understand the concept of mass or Newton's Laws.
