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 Energy

Chemical 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.
