Final answer:
Mass, volume, and density are key physical properties studied in physics. Mass is the amount of matter in an object, volume is the space it occupies, and density is mass per unit volume, determining if an object will float or sink.
Step-by-step explanation:
The concepts of mass, volume, and density are fundamental in physics, particularly when understanding the properties of matter. Mass is a measure of the amount of material in an object and does not change regardless of its location. Volume, typically measured in cubic units, refers to the amount of space that an object occupies. Density is a crucial concept that defines the mass per unit volume of a substance, calculated by dividing the mass by the volume.
To determine the density of a material, one would measure the mass and volume of the object separately and then compute the quotient of the two. This measure allows comparisons between the densities of different materials and helps explain phenomena like why certain objects float in water.
