What do you know about the history of Energy ?

Our honor ancient Arab scientists in Energy fields

» Al RazyIn forces and energy conversion calculation .

» Al JazariHe used mechanics and water for converting energy from one form to another.

» Gaber Ebn-HayanChemical energy analysis foundation and construct of its conversions.

Our honor ancient Arab scientists in Energy fields

» Al-HaysamElectromagnetic energy analysis and light construction description.

Energy types » Transitional EnergyEnergy in motion , across all system boundariesEx: current, work and heat.

» Stored EnergyExist as mass , position in force field and can transfer to transition form

Ex: potential energy and hydraulic dames

Heat Energy» Internal motion of the atoms

» Produced by friction.

» Changes in temperature and phase of any

matter.

Chemical Energy» Bond atoms together.

» And when bonds are broken, energy is

released.

» Fuel and food are forms of stored chemical

energy.

Electromagnetic Energy» Light is a form of electromagnetic energy.

» Rainbow effect.

» X-rays, radio waves, and laser light.

Nuclear Energy

» The nucleus of an atom is the source of nuclear energy.

» Fission and Fusion in atoms act and related with sun reactions.

Mechanical Energy

» When work is done to an object, it

acquires energy.

» Kicking a football, is a mechanical

energy.

Solar Energy

Two Applications

• Uses Semiconductor which has free electrons liberated when photons falls on it and generate electricity.

Solar cells

• Solar rays are concentrated to a single area to heat water which converted into steam to generate energy.
