Energy ReviewPhysical Science
The Equations!
Kinetic Energy =
Gravitational Potential Energy = m g h
Conservation of Energy!Important Equation
Energy can be neither created nor destroyed but only conserved.
Common Forms of EnergyPotential and Kinetic (aka mechanical)ThermalChemicalElectrical (kind of)Electromagnetic Nuclear
Methods of Energy ProductionNonrenewable (fossil fuels, natural gas, etc.)
Hydroelectric Plants
Geothermal Plants
Methods Cont.Solar Cells and Panels
Wind Turbines!
Ideal System (aka a perfect world)Energy is not lost to friction or leaking.
In short energy is conserved and perpetual motion works
Real WorldEnergy is lost to friction
Energy is lost to the production of other forms in conversion processes (such as sound and heat)
Energy is still conserved just we can convert 100% of it into the intended form
