The density of an object is calculated by dividing the mass by the volume. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

Density describes how much space an object or substance takes up in relation to the amount of matter in that object or substance. It’s the objects volume in relation to its mass. Another way to ...

The experiments also serve to illustrate Dirac's Plate Trick, which posits that a rotating object with strings has to rotate twice to return to its original state.

The units of density depend on the units used for mass and volume. The most commonly used units are grams per cubic centimetre (g/cm³) or kilograms per cubic metre (kg/m³). These balloons are the same ...
