Understanding Mass, Weight, Density, and Volume

Massiveness is a measure of the amount of matter that an object contains. It is a fundamental property of an object, and it determines how much space the object occupies and how much gravity it exerts on other objects.

2. What is weight ?

Weight is the force exerted on an object by gravity. It is the amount of gravitational pull that acts on an object, and it depends on both the mass of the object and the strength of the gravitational field it is in. Weight is different from mass, as weight can change depending on the location of the object, while mass remains constant regardless of location.

3. What is density ?

Density is a measure of how much mass is contained in a given volume of an object. It is calculated by dividing the mass of an object by its volume. Density is an important property of objects, as it determines many of their physical properties, such as buoyancy and thermal conductivity.

4. What is specific gravity ?

Specific gravity is a measure of the density of a substance relative to the density of water. It is calculated by dividing the density of the substance by the density of water. Specific gravity is often used to determine the buoyancy of objects in liquid, as well as their ability to float or sink.

5. What is volume ?

Volume is the amount of space occupied by an object. It is measured in cubic units, such as cubic centimeters (cm³) or cubic meters (m³). Volume is an important property of objects, as it determines how much space they occupy and how much matter they contain.
