Measure of the voltage. If you wish to measure the voltage in an electric circuit, you need a measuring device (multimeter)

Vectors are a great help when you have to represent different physical magnitudes.

Los vectores resultan de una gran ayuda a la hora de representar diferentes magnitudes físicas.

Units of measurement indicate what is being measured. The number which precedes the unit of measurement indicates how much it measures.

La trayectoria de un movimiento permite conocer qué camino siguió el móvil.

El ODE muestra información acerca del movimiento de la Tierra alrededor del Sol y el efecto que éste movimiento provoca produciendo variaciones cíclicas en la temperatura que agrupamos en cuatro estaciones. Se acompaña con una escena donde se puede observar el eje de rotación de la Tierra está inclinado.

Classification of movements according to their trajectory and speed.

The trajectory of a movement is the path the moving body followed.

The educational resource shows information about the concept tidal energy and its advantages and its disadvantages.

The educational resource shows information about the concept of thermal energy: thermal energy is due to the movement of the particles which make up matter.

The educational resource shows a visual: it is a simulation of the solar system, you can select the planet you want to see and also vary the plane of the orbits.

The educational resource shows a visual about the solar system: the solar system is formed by the sun and all the astronomical bodies which orbit around it.

The educational resource shows a visual about the signs of Zodiac: every year, the earth goes once round the Sun and as this movement is carried out, from the earth we see the sky in a similar way at the same time of year. This is the basis of Astrology.The following visual shows what the Zodiac has to do with the annual movement of the Earth.

The educational resource shows a visual about the planets: in addition to our planet, there are another eight planets travelling around the sun.

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

The educational resource shows how the energy is the capacity to produce changes in the environment by doing work or transferring heat. This means that when a body transfers heat or does work, its energy decreases.

In the following visual you can observe how the rotational axis of the earth is inclined; when the North Pole is furthest from the sun, the South Pole is nearest the sun and vice versa.

The following visual explains the precautions that should be taken into account when dealing with electricity

The educational resource shows a Flash animation about the greenhouse effect The Earth is an open material system, because it interchanges matter and energy with outer space.

The study of matter allows us to encompass the known universe in a range of sizes and distances with lower and upper bounds.
