Energy Powerpoint- States, Types and Transfer

Energy

What is energy?Energy is the ability to do work.Law of Conservation of Energy Energy cannot be created or destroyed. There are two states of energy or types of energy . Potential and kinetic. Potential Potential is stored energy

Kinetic Kinetic is the energy of motion.

There are five main forms of energy. ChemicalMechanical ElectromagneticHeat (thermal)NuclearChemical Energy Energy that is available for release from chemical reactions.

Mechanical Energy Energy due to a objects motion (kinetic) or position (potential).

ElectromagneticLight energy

Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bandsMoving electric charges

Heat or Thermal Internal motion of atoms. The heat energy of an object determines how active its atoms are.

Nuclear Nuclear energy is the energy stored in the nucleus of an atom and can be broken into:fusion (energy of the sun which is the combing of two or more nuclei) and fission(the splitting of an atom like in a nuclear reactor).

Energy Transfer

ChemicalElectricalElectricalElectricalSound(mechanical)Light(Electromagnetic)ThermalMechanical

There are three types of (energy) heat transfer.ConvectionConductionRadiation

Convection Convection is the transfer of heat energy in a gas or liquid by movement of currents due to changes in density. Conduction is the transfer of energy through matter from particle to particle.RadiationAllows heat to be transferred through wave energy.

Renewable

Renewable resources are those resources that can be replaced as they are used up. Some examples include:soil air water wood sunlight

Non-Renewable

Nonrenewable resource are those natural resources that cannot be replaced once they are used up. Some examples include:oil coal gas uranium
