Elements that make up a mirror: the optical axis, the centre of curvature and the focal point of a mirror.

The educational resource shows information about the kinetic energy: the kinetic energy of an object is its capacity to change its environment, because it is moving. How far will two balls with different masses and velocities penetrate a block of snow?

The small automatic switches (SAS) are elements of a consumer unit

Concept of angular and linear displacements

The educational resource shows an interactive animation about the latent heat concept: the energy needed to produce a change of phase per unit mass is known as latent heat.

Concept for measuring the forces. Dynamometer

Concept of beta particles

The educational resource shows a visual about the free fall in air: when a body falls through a fluid such as air, its shape is important.

Concept of acceleration (I)

Concept of particle in an infinite well

The educational resource shows information about the concept of chemical energy: chemical energy is what is produced in chemical reactions. An energy cell or a battery possess this type of energy. The gas burning in a cigarette lighter shows how the chemical energy contained in the gas is transformed into light and heat.

The electricity consumption

Concept of half-life

Concept of frame of reference

The lines of force in magnetic fields.

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

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.

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
