ENERGY AND ENERGY RESOURCES
Essential Question:
What are the types of energy and how is energy conserved?
Vocabulary Energy Chemical Energy Electrical Energy Nuclear Energy Radiant Energy Thermal Energy Kinetic Energy Potential Energy Generator Motor Turbine
Law of Conservation of Energy
Alternative Resources
Inexhaustible Resource
Nonrenewable Resource
Renewable Resource Photovoltaic
The Law of Conservation of EnergyEnergy is never created or destroyed it
just changes form
EnergyThe ability to cause change.
Types of EnergyChemical Energy- the energy stored in chemical bonds.
Nuclear Energy- the energy in the nucleus of every atom.
Types of Energy
Thermal Energy- the energy of an object that increases as temperature increases.
Radiant Energy- the energy carried by light.
Convection- the transfer of thermal energy through the movement of molecules from one part of a material to another.
Cold Sinks
Creates a Circular Current
Heat Rises
Types of Energy
Electrical Energy- the energy carried by electrical current that comes out of batteries or electrical outlets.
Kinetic Energy- the energy an object has because of its motion
Converting Energy
Generator- a device that transforms kinetic energy into electrical energy.
Motor- a device that transforms electrical energy into kinetic energy.
Types of Energy Potential Energy- energy that is
stored in an object because of its position
Renewable and Nonrenewable Resources
Gasoline is a nonrenewable resource.
Wood is a renewable resource.
Inexhaustible Resource- an energy source that cannot be used up by humans.
The Sun is an Inexhaustible Resource because we cannot use up that energy.
Alternative Resources- new renewable or inexhaustible resources.
Wind to generate energy.
The sun to power and heat houses
Electrical Energy to Power Transportation
Generating Energy
Turbine- a set of steam powered fan blades that spins a generator at a power plant.
Photovoltaic- a device that transforms radiant energy directly into electrical energy.
