The video tutorial introduces the concept of density, explaining it as the relationship between mass and volume. It uses examples of wood and copper to illustrate differences in density. The tutorial covers the formula for density and its rearrangements to calculate mass and volume. Three examples are provided: calculating the density of a metal piece, finding the volume of an iron statue, and determining the mass of a glass cylinder. The tutorial emphasizes the importance of using correct units and provides step-by-step calculations.
