The educational resource shows a visual about the work: in Physics, for there to be work there must be a force acting on an object and displacement of the object.

Concept of radioactivity. Radioactivity is the property which certain substances have for emitting radiation.

Friction concept

Concept of Waves in the sea. The waves on the sea or those which form on any surface of water, are a special instance of undulatory movement.

Concept of wavefront: wavefront is the locus of points characterized by propagation of positions of identical phase.

Concept of wave function: there is a mathematical function associated with every particle which behaves like the functions of other undulatory phenomena.

Concept of wave equation

La vida media representa el promedio de vida de un núcleo atómico de una muestra radiactiva.

Concepto de velocidad y masa de los electrones. Cuando sobre un tubo de rayos catódicos se sitúan un campo eléctrico y otro magnético, perpendiculares, puede estudiarse de manera cuantitativa las propiedades de los electrones: su velocidad, su carga y la relación carga/masa.

A particle which oscillates around a point of equilibrium, subject to a force proportional to the distance to this point, has a simple harmonic vibratory movement.

Concepto de vector desplazamiento

La velocidad angular es una medida de la velocidad de rotación.

¿A qué velocidad debe salir un satélite para vencer la gravedad terreste y escaparse de ella?

Concept of Uniform Rectilinear Motion

Concept of Uniformly Accelerated Rectilinear Motion. What is a uniformly accelerated movement?

What is a uniform circular movement?

Types of spherical mirrors. spherical mirror is a reflecting surface which could be formed like a section of a sphere separated from the rest by a plane. There are two types of spherical mirrors: concave and convex.

Concept of twins paradox
