Physic Lab Cubes.

Practice #1

Density is the mass of a substance per unit of volume, so if you measure both mass and volume of a given sample, you can calculate its density by dividing mass by volume.

Procedure
1. We weighed and measured the 5 types of cubes in order to calculate the density of each one.
2. We calculated the volume (v) of each cube with the formule v: L*L*L, we obtained the L measuring the cube faces.
3. We calculated the density of each cube with the formule p: m/v, we obtained the mass of each cube (m) weighing each cube.

Observations
As a result we observed that all the cubes had the same or nearly the same measure in size, however the difference in weigh was notable because the cubes were made of different materials, some heavier than others.So the volume and density of the cubes was also variable.

Physical Explanation

An object's density is determined by comparing its mass to its volume. If you compare a rock and a cork that are the same size (they have equal volume), which is heavier? The rock is, because it has more mass. The rock is denser than the cork, then, because it has more mass in the same volume - this is due to the atomic structure of the elements, molecules, and compounds that make it up.
