what do density in physics mean

In physics, density is a measure of mass per unit volume of a material or object. Here’s what you need to know about it:

1. Definition: Density is calculated by dividing the mass of an object or substance by its volume. Mathematically, it is represented as ( \text{Density} = \frac{\text{Mass}}{\text{Volume}} ).

2. Units: The SI unit for density is kilograms per cubic meter (kg/m³), but other units like grams per cubic centimeter (g/cm³) are also commonly used.

3. Material Properties: Density is a characteristic property of a material, which means different materials typically have different densities, even if they have the same mass
