Electric energy is changed to sound energy by a electromagnetic transducer, a speaker. The speaker moves a magnet that moves the air.
As the electron moves nearer the nucleus the energy level of the electron decreases.
When the object moves, its potential energy is converted into kinetic energy.
IT moves faster
Potential energy is transformed into kinetic energy, the water speeds up.
A change of state involves a gain or loss of heat energy.
Kinetic energy increases as an object moves faster. An objects' kinetic energy will only change if the force acting on the object changes the object's speed.

The energy is said to be given off as a photon of light.
The potential energy of electrons decreases while Kinetic energy becomes increased the overall effect is the decrease in energy.
