The force of gravity on an object is referred to as which of the following?

The force of gravity acting on an object is known as weight. Weight is a measure of the gravitational pull exerted on an object by the Earth (or another celestial body), and it is calculated by multiplying the mass of the object by the acceleration due to gravity (approximately 9.81 m/s² on Earth). This means that weight is a force, and it is commonly expressed in units such as newtons (N) or pounds (lbs).

In contrast, mass refers to the amount of matter in an object and remains constant regardless of location; it is measured in kilograms (kg) or grams (g). Inertia is related to mass and is the property of an object to resist changes in its state of motion, meaning a heavier object (greater mass) would require more force to change its motion. Density describes how much mass is contained in a given volume of an object, typically measured in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³). Each of these concepts provides valuable information about matter, but it is weight that specifically correlates with the gravitational force on an object.
