TYPES OF ENERGYJ

The energy an object has because it is moving.Vibrating objects are sources for this energy.Forms of energy that are waiting to be used.Food is an example of this.This energy is available every time a current flows.Winding up a spring will give it this type of energy.One type of energy changes into another type of energy.The energy an object has when it is high up.JGravitational potential energyStored energySound energyElectrical energyKinetic energyChemical energyElastic potential energyEnergy transfer

THE LAW OF CONSERVATION OF ENERGY

A light bulb changes electrical energy into and energy.

The car changes energy into .. energy and energy.

The CD player and loudspeakers changes .. energy into energy.

A log fire changes energy into heat and energy.

**energy can be transformed into another type of energy but it cannot be created and it cannot be destroyed. Concepto de degradacin: la degradacin de la energa es el paso de formas tiles de energa a otras no aprovechables= when energy is used it doesnt dissapear, it is transferred into other differents forms of energy*Every day you use equipment which converts between energy types. For example a light bulb converts electrical energy to light energy. A car converts chemical energy to kinetic energy. ***************
