The educational resource shows a visual about the movement of electric charges: the visual shows a capacitor where the intensity of an electric field bewteen its plates is practically constant. This area is a good place to study how the charges inside an electric field move.

Concept of absolute error

Concept of wave amplitude

Concepts of analysis and interpretation of results within the scientific method

Concept of attraction among masses

The educational resource shows a visual about artificial satellites: they are indispensable nowadays. In this visual you can study the movement of an artificial satellite around the Earth.

Concept angular velocity

Concept of Absorption

Concept of Bohr's atomic model

Concept of ascent and descent of an object

Concept of artificial radioactive series

The movement of the electrons inside an electrical conductor of oscillating form.

Concept of attraction among masses

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 different, g would also be different.
