Question

Quizplus · Accepted Answer

Weight is the force of gravity acting on an object, which is dependent on both the object's mass and the gravitational pull of the planet. The gravitational pull depends on the mass and radius of the planet, and since Mars and Earth have different masses and radii, the weight of an object with the same mass will be different on each planet.
