5.Gravitational acceleration is:

Forms of Energy

●Mechanical Energy:

●Energy of moving objects

●The sum of potential and kinetic energies

Forms of Energy

Thermal Energy:

●Energy stored in molecules colliding

Increased collisions, more energy, feels warmer

Forms of Energy

●Chemical Energy:

●Energy stored in chemical bonds

●When bonds are broken, energy is released

Forms of Energy

●Electrical Energy:

●Energy of electric charges

●Electrons pass through an object to create energy

Forms of Energy

• ●Electromagnetic Energy:

  ●Energy that travels through space in waveform

  ●Examples: Visible light,        x-rays, radio waves

Forms of Energy

●Nuclear Energy:

●Energy stored in a nucleus

●Examples: Fission & Fusion

Energy Conversion

• ●Conversion

  ●Energy changes from one form to another

  ●What occurs in lighting a match?

Law of Conservation of Energy

●Energy cannot be created or destroyed, only converted

●Gravitational Potential Energy changes to kinetic energy as the object begins to move

Energy Resources

●Nonrenewable Energy Resources:

●Cannot be easily recreated, takes millions of years

●Fairly cheap, readily available, but create pollution

●Examples: Fossil Fuels (oil), Natural Gas, Coal, Uranium

Energy Resources

• ●Renewable Energy Resources

  ●Can be easily replaced

  ●Come either directly or indirectly from the sun

  ●Examples: Hydroelectric, Solar, Geothermal, Wind, Biomass

Types of Energy Foldable

●Complete the Dichotomous Key of Energy Sources (note sources and types are not the same)

Cut out the foldable (see example)

●Add the pictures to the correct type

●Add the definition to the correct type

●CHECK your work!!! (the key is on my desk)
