SHM: What is it?
If you want to know what a Simple Harmonic Motion is, you should learn some terms.
Contexto educativoTipo de recursoColecciones -
SHM: acceleration
This visual is interesting as it shows how the acceleration of a simple harmonic movement varies.
Contexto educativoTipo de recursoColecciones -
SHM: fundamental magnitudes
Important physical magnitudes in the description of the simple harmonic movement.
Contexto educativoTipo de recursoColecciones -
SHM: phase difference
The concept of "phase difference" is fundamental when studying simple harmonic movement. Study this carefully.
Contexto educativoTipo de recursoColecciones -
SHM: position
Concept of the position in a simple harmonic motion
Contexto educativoTipo de recursoColecciones -
SHM: velocity
In a simple harmonic motion the velocity changes, as you can see in the visual.
Contexto educativoTipo de recursoColecciones -
SHM: representation
Representing the simple harmonic motion in a visual

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

Reflection
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.

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

Representation of forces
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
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.

Relativistic paradox
If at relativistic speeds bodies decrease in length, would it be possible to shut a large rocket which was travelling at the speed of light in a hangar? The answer to this question constitutes a "relativistic paradox".
Contexto educativoTipo de recursoColecciones -
Refraction
Imagine that a wave passes from a deeper zone to another shallow zone, or vice versa. There will be refraction.

Radians: what are they?
Angles can be measured with sexagesimal degrees. A right angle is equal to 90 degrees. Radians are another way of measuring angles.
Contexto educativoTipo de recursoColecciones -
Radioactive constant
The radioactive constant or decay constant, is a coefficient of proportionality which relates the atoms which disappear in a period of time t, with the initial atoms for each radioactive nuclide.
