Essential Question: What are the types of energy and how is energy conserved? Energy and Energy Resources
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
EnergyThe ability to cause change. • The Law of Conservation of Energy Energy is never created or destroyed it just changes form
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. The sun to power and heat houses Electrical Energy to Power Transportation Wind to generate energy.
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.
