  • 1. All About Energy By: Rachael Shapiro Luke Richards & Sydney Flagg Solar energy Chemical energy Mechanical energy & Electrical energy Thermal energy Motion energy Sound energy
  • 2. What is Energy?
    • Energy is the ability to do work. Energy is in everything everyday! We use energy without even knowing it.
    • There are two types of energy: potential and kinetic.

  • 3. Forms of Energy
    • The forms of energy are light, heat, chemical, and motion. There are many forms of energy, but they can all be put into two categories: Potential and Kinetic.
    Potential energy Kinetic energy
  • 4. Potential Energy Potential energy- Potential energy is energy which results from position or configuration. An object may have the capacity for doing work as a result of its position in a gravitational field (gravitational potential energy), an electric field (electric potential energy), or a magnetic field (magnetic potential energy). It may have elastic potential energy as a result of a stretched spring or other elastic deformation.
  • 5. Forms of Potential Energy
    • Chemical Energy- is converted to thermal energy when we burn wood in a fireplace or burn gasoline in a car's engine.
    • Mechanical Energy- energy stored in objects tension. Rubber bands and springs are examples of stored mechanical energy.
    • Nuclear energy and
    • Electrical energy.
  • 6. Forms of Kinetic Energy
    • Radiant Energy- is electromagnetic energy that travels in transverse waves.
    • Thermal Energy- or heat, is the vibration and movements of atoms and molecules within substances.
    • Motion Energy- is energy stored in the movements of objects.
    • Sound Energy- the movement of energy through substances in longitudinal waves.
  • 7. Energy Sources
    • There are 2 types of energy sources: nonrenewable and renewable. Energy sources are considered nonrenewable if they cannot be replenished (made again) in a short period of time. On the other hand, renewable energy sources such as solar and wind can be replenished naturally in a short period of time.
    • Nonrenewable Energy-
    • Renewable Energy-
  • 8. Renewable Energy
    • Sources can be replenished in a short period of time. The five renewable sources most used are:
    • Biomass- including wood and wood waste, municipal solid waste, landfill gas, and biogas, ethanol and biodiesel.
    • Water (hydropower)
    • Geothermal Wind
    • Wind Solar
    • Solar
  • 9. Nonrenewable Energy
    • The 4 nonrenewable energy sources used most often are:
    • Oil and Petroleum products- gasoline, diesel fuel, and propane
    • Natural gas
    • Uraniam (Nuclear Energy)
  • 10. Energy Transformation
    • Examples-
    • Human body- like a machine and fuel for your machine is food.
    • Cars- gas is the fuel.
  • 11. Questions? How many types of energy are there? A: two B: five C: one D: Answer not above
  • 12. Questions? Energy stored in the movements of objects is the definition of what kind of energy? A: Motion Energy B: Kinetic Energy C: Radiant Energy D: Thermal Energy
