The measurement that is affected by gravity is Weight.
Weight is the force exerted by gravity on an object and is calculated as the mass of the object multiplied by the acceleration due to gravity. In contrast, mass is a measure of the amount of matter in an object and remains constant regardless of gravitational pull. Density, which is mass per unit volume, is also not directly affected by gravity. Inertia is a property of matter related to mass and does not change with gravity.
