Carnot´s ideal engine

The educational resource shows an interactive animation about the Carnot's engine: it is a theoretical model, not a real one, but we can already see in it the fundamental characteristics of real heat ...

Thermal equilibrium

The educational resource shows an interactive animation about the thermal equilibrium: when two substances at different temperatures are in contact, they exchange a certain amount of energy. One's tem ...

The heating curve

The educational resource shows an interactive animation about the heating curve: when a body is heated, its temperature increases until there is a change of state; while the change takes place, the te ...

Temperature scales

The educational resource shows an interactive animation about tempereture scales: there are various ways of expressing what the temperature of a body is. Each system is known as a temperature scale.

Fixed stars

The educational resource shows a visual about fixed stars: today we know that the sun is no more than a star which is near to us. Stars like the sun, which are large gaseous spheres, of which 99% is h ...

Lunar phases

The educational resource shows a visual about lunar phases: the moon is a rocky sphere about four times smaller than the earth. Its different aspects (as seen from the earth) are known as lunar phases ...

Electric field intensity II

The educational resource shows a visual about the intensity of the electric field:What are the lines of force like in a field created by two electric charges?

The principle of superposition (I)

The educational resource shows a visual about the principle of superposition: when we talk about systems with more than two bodies, we have to bear in mind the Principle of superposition of forces: th ...

Gravitatonial potential energy

The educational resource shows a visual about gravitational potential energy: the calculation of gravitational potential energy is very easy for small heights, as it is given by the formula Ep=mgh, wh ...

The variable intensity of gravity

The educational resource shows a visual about the variable intensity of gravity: the intensity of gravity, g, is not a true constant, as it changes with altitude.
