Kinetic & Potential
Potential -> Kinetic
Creating electricity using the power of moving water
Hydro
Stored energy, can be related to position
Potential Energy
Energy found in the nucleus of atoms
Energy found in food, and oil
Chemical
A basketball bouncing on the ground
Kinetic -> Thermal
Biomass / Biofuel
The energy of movement
Energy stored in the bonds of molecules
Chemical Energy
This energy is used in the heart of the sun to create its light and heat
Nuclear Energy
Splitting uranium atoms to produce power at a power plant
Nuclear -> Electrical
Heat from the ground is used to generate electricity
Geothermal
If a motorcycle and a car are moving at the same speed, which one has the higher kinetic energy?
Car - It is heavier!
Energy created by the movement of electrons
Electrical Energy
Sound is classified as
Thermal Energy
Electrical -> Light + Thermal
The most commonly used power source in the world
Coal
The first law of thermodynamics
Energy cannot be created or destroyed
Energy from the movement of electromagnetic waves
Radiant Energy
Radio signals are an example of this
Radiant Energy
Energy produced by the sun
Nuclear -> Radiant + Thermal
The most efficient power source
