Change of phase

The educational resource shows an interactive animation about the change of phase: solids melt when they are heated and liquids evaporate, changing to a gaseous state. If you increase the vibration of ...

Equilibrium between different states

The educational resource shows an interactive animation about the equilibrium between different states: a substance (water, for example) in different states at different temperatures (ice and water) w ...

The principle of superposition (II)

The educational resource shows a visual about the intensity of the electric field: a body's electric charge alters the space which surrounds it. The magnitude which measures this alteration at a deter ...

Apparent gravity

The educational resource shows a visual about the apparent gravity: the gravitational field intensity, g, is not the same everywhere on the surface of the earth. If the period of the rotation were dif ...

Kepler´s laws

The educational resource shows a visual about Kepler´s laws: Kepler used as his basis, both the results of his observations and those of his Astronomy professor, Tycho Brahe, "the last geocentric astr ...

Electric potential and work

The educational resource shows a visual about the relation between field intensity and potential: the work carried out by the field when a charged particle q moves from one point to another, only depe ...

Measuring g

The educational resource shows a visual about the measurement of g: a simple pendulum is sufficient to measure the intensity of the gravitational field g. Before beginning the experiment, invent some ...

The Milky way

The educational resource shows a visual about the Milky way: you can manipulate our galaxy in the following visual to see its characterstics.

Chemical energy

The educational resource shows information about the concept of chemical energy: chemical energy is what is produced in chemical reactions. An energy cell or a battery possess this type of energy. The ...

Mass and weight

The educational resource shows a visual about the difference between mass and weight: mass is not the same as weight, although in ordinary life both words are used with the same meaning. In Physics, m ...
