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 ...

Conservation of energy (I)

The theorem of conservation of mechanical energy states that the work carried out on a body is invested exactly in increasing some type of energy. When a there are only conservative forces in a system ...

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 ...

What is work? (II)

Work is one of the ways of transmitting energy between bodies. The following visual will help you understand the concept of work by modifying the force and the angle which it forms with the horizontal ...

Work carried out by a pendulum

The following visual studies the work done by a pendulum: it is difficult to calculate as the force which acts on it varies constantly. If you select Table and start the animation you will be able to ...

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 ...

Kinetic energy

The educational resource shows information about the kinetic energy: the kinetic energy of an object is its capacity to change its environment, because it is moving. How far will two balls with differ ...
