Mechanical energy is what is produced by mechanical type forces, like elastic and gravitational forces.The following three pictures show situations involving mechanical energy.
The movement of electrons inside a conductor .
The theorem of live forces establishes that the work carried out by the forces acting on a system, is equal to its kinetic energy. The force which acts on the train in the visual is invested into incr ...
Concept of particle in an infinite well
When we stretch a spring, the work we carry out varies as we stretch it because the force we have to exert at every instant is constantly varied. The force which has to be exerted must compensate for ...
The educational resource shows a visual about the conservation of energy: the sum of the kinetic energy and the potential energy of a body (mechanical energy) remains constant, provided there are no f ...
The educational resource shows a visual that represents a capacitor, a system made up of two conducting plates with equal charges, but with opposite signs, separated by an insulator or a vacuum. Insid ...
In this teaching unit you will learn: To describe qualitatively the phenomena of electrification, electrostatic attraction and repulsion and to introduce the concepts of electric charge, insulators an ...
Teaching unit work and energy for 4 º ESO. Work (W). Energy. Work and energy. Power (P) of a force / machine.
Prueba a lanzar un haz de luz (fotones) sobre un material (metal) y verás cómo se desprenden electrones (fotoelectrones).
Comprueba:
qué efectos sobre la intens ...
