Trajectory depending on the RS (I)
The trajectory of a moving body varies depending on the reference system it is seen from.

Trabajo realizado por un péndulo
Concepto de trabajo realizado por un péndulo. El ODE muestra una escena interactiva donde se puede comprobar cómo el trabajo que realiza un péndulo varía constantemente.
Contexto educativoTipo de recursoCollections -
Trabajo de rozamiento
Concepto de trabajo de rozamiento. El ODE muestra una escena donde sobre un bloque actúa una fuerza que lo desplaza horizontalmente. Se permite la intervención o no de una fuerza de rozamiento, modificando la rugosidad del suelo. Asimismo se puede modificar la dirección de la fuerza que actúa.

Trabajo al estirar un resorte
Concepto de trabajo al estirar un resorte. El ODE muestra una escena interactiva que simula la fuerza que ejerce un alumno sobre un muelle. En la escena se representa el valor de la fuerza elástica, el desplazamiento y el trabajo que se desarrolla. Se permite cambiar el valor de la constante elástica.

Total reflection
When a ray of light goes through a sheet of glass, it is refracted. In certain circumstances there can be total reflection.

Tipos de espejos
Un espejo esférico es una superficie reflectante que podría formarse como una sección de una esfera separada del resto por un plano. Hay dos tipos de espejos esféricos: los cóncavos y los convexos.

Tipos de lentes
Una lente esférica es un cuerpo transparente formado por dos caras esféricas. Esta escena permite ver los tipos de lentes que existen.

Tides
The educational resource shows a visual about tides: the effect of the gravitational force of the moon and the sun on the earth can be seen in the tides.
Contexto educativoTipo de recursoCollections -
Tidal energy
The educational resource shows information about the concept tidal energy and its advantages and its disadvantages.

Telescope (optics)
Suitable lenses, correctly combined, as in the following visual can help you to understand how a telescope works.

The uncertainty principle
Heisenberg showed that measuring the magnitude of a quantum particle altered its state, so that another magnitude could not be measured simultaneously
Contexto educativoTipo de recursoCollections -
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.
Contexto educativoTipo de recursoCollections -
The thermometer
The educational resource shows an interactive animation about the thermometer: the fact that mercury and alcohol expand when the temperature increases is used to construct thermometers.
Contexto educativoTipo de recursoCollections -
The television
The cathode ray tube gave rise to an application which had an application that became very popular in the second half of the twentieth century: television.

The solar system (theories)
The educational resource shows a visual about the solar system: What is at the centre, the sun or the earth? This question has been asked since the beginnings of humanity. The answer is found in the different models of the solar system.
Contexto educativoTipo de recursoCollections -
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: the force exerted by one body on another is independent of that exerted by the rest.

The shape of galaxies
The educational resource shows a visual about the shape of galaxies: what causes the variety of shapes among galaxies? Some are spiral galaxies, others are elliptical or spherical.
Área de conocimientoContexto educativoTipo de recursoCollections -
The mechanical equivalent of heat
The educational resource shows an interactive animation about the mechanical equivalent of heat.
Contexto educativoTipo de recursoCollections -
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 temperature remains constant.
