Final answer:
Density is a measure of how much mass there is per unit volume. It is calculated by dividing the mass of an object by its volume. If the mass increases and the volume remains constant, the density will increase. Likewise, if the volume increases and the mass remains constant, the density will decrease.
Step-by-step explanation:
In physics, density is a measure of how much mass there is per unit volume. The volume of an object is the measure of the physical space it occupies, while the mass is a measure of the amount of material within an object. To determine the density of a substance, we divide its mass by its volume.
For example, if we have a sample with a mass of 100 grams and a volume of 50 cubic centimeters, we can calculate the density by dividing the mass by the volume: density = mass/volume = 100g/50 cm^3 = 2 g/cm^3.
Thus, density relates to the mass and volume of an object. If the mass of an object increases while the volume remains constant, the density will increase. Similarly, if the volume of an object increases while the mass remains constant, the density will decrease.
