The speed with which work is done is called power. To lift the same object to the top implies carrying out the same amount of work. To lift it at a different speed, implies using a different amount of power.

The educational resource shows a visual about the potential energy: two balls are on the point of falling, they possess gravitational potential energy. When they reach the snow they will modify their state. What will this depend on?

The atoms are usually neutral state. The agitation of a gas increases when it absorbs heat. If enough heat is absorbed, electrons are stripped from atoms and matter is ionized, saying that it is in plasma state.

Concepto de plasma. Estado de plasma. Descripción del estado de agregación de la materia denominado plasma

Light behaves in two ways: like a particle and like a wave. The way a photoelectric cell works shows the corpuscular behaviour of light.
