Energy Review

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
