The educational resource shows an interactive animation about the specific heat concept: when a body is heated, the temperature it finally reaches depends on the nature of the body. This property is known as specific heat.

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

Soddy and Fajans stated the laws of transmutation which govern the process by which one element transmutes into another. Soddy's 2nd law: When a radioactive atom emits a beta particle, its atomic number increases by one unit.

Soddy and Fajans stated the laws of transmutation which govern the process by which one element transmutes into another.

When an electric current of variable intensity circulates through a coil an induced current originates inside it.

The description of a simple harmonic motion can be carried out more easily by using an auxiliary uniform circular movement.

If you want to know what a Simple Harmonic Motion is, you should learn some terms.

This visual is interesting as it shows how the acceleration of a simple harmonic movement varies.

Important physical magnitudes in the description of the simple harmonic movement.

The concept of "phase difference" is fundamental when studying simple harmonic movement. Study this carefully.

Concept of the position in a simple harmonic motion

In a simple harmonic motion the velocity changes, as you can see in the visual.

Representing the simple harmonic motion in a visual

The material world which our eyes cannot observe is known as the microscopic scale of observation (cells, atoms, molecules, etc.)

Which is going faster? The s/t and v/t graphs together or separately.

The speed of an MCU can be expressed in rpm and in rps (revolutions per minute and revolutions per second).

When an undulatory movement comes across an obstacle which prevents its propagation and does not absorb its energy, the waves change direction, they are reflected.

The residual current circuit breaker (RCCB) is one of the elements of a consumer unit. The following visual explains its function.

Forces are represented by means of vectors. A vector is an oriented sector. The following animation representes the characteristics of a vector.

Renewable energy sources are those which after being used can be regenerated naturally or artificially. The following pictures are graphic examples rof enewable energy sources.
