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. Chemical Mechanical Electromagnetic Heat (thermal) Nuclear
Chemical Energy Energy that is available for release from chemical reactions.
Mechanical Energy Energy due to a object’s motion (kinetic) or position (potential).
Moving electric charges Electromagnetic Light energy Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands Moving 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 Sound (mechanical) Electrical Thermal Mechanical Chemical Electrical Light (Electromagnetic)
There are three types of (energy) heat transfer. Convection Conduction Radiation
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.
Radiation Allows 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
In fact ….. NOTHING would happen without ENERGY
