Concept of half-life

Concept of instantaneous velocity

Concepto de factores de conversión. Fracción en la que el numerador y el denominador valen lo mismo (son valores iguales expresados en unidades distintas)

The area of the graph between the curve F and the X axis, represents the work carried out by the force between the two positions x0 and x. Review how to use the following visual and carry out the two proposed activities for a better understanding.

Concept of frame of reference

The lines of force in magnetic fields.

The educational resource shows a visual about the intensity of the electric field: What are the lines of force in a field created by two electric charges?

Magnetic field on the inside and near the poles of a long solenoid.

The educational resource shows a visual about the graphically represent the electric field: we use the concept of lines of force.

Concepto de observación

Concepts of analysis and interpretation of results within the scientific method

Concept of law of refraction.

The educational resource shows a visual about gravitational potential energy: the calculation of gravitational potential energy is very easy for small heights.

Concept of attraction among masses

Concepto de coeficiente de rozamiento dinámico.

Concepto de aceleración en el movimiento circular uniforme

Archimedes' principle is a principle of physics that states that a body wholly or partially submerged in a static fluid, will be pushed with a vertical upward force equal to the weight of the volume of fluid displaced by the body

Concepto de la caída de un cuerpo en el vacío. El ODE muestra una animación donde se puede estudiar la caída de un objeto en el vacío. Se puede modificar la altura desde donde cae, la forma (esférica, apuntada o plana) y la masa del objeto. A la vez que cae se dibuja una gráfica posición-tiempo.
