  1. 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. 2. What is Energy? <ul><li>Energy is the ability to do work. Energy is in everything everyday! We use energy without even knowing it. </li></ul><ul><li>There are two types of energy: potential and kinetic. </li></ul><ul><li>http://www.youtube.com/watch?v=kw_4Loo1HR4 Video </li></ul>
  3. 3. Forms of Energy <ul><li>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. </li></ul>Potential energy Kinetic energy
  4. 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. 5. Forms of Potential Energy <ul><li>Chemical Energy- is converted to thermal energy when we burn wood in a fireplace or burn gasoline in a car's engine. </li></ul><ul><li>Mechanical Energy- energy stored in objects tension. Rubber bands and springs are examples of stored mechanical energy. </li></ul><ul><li>Nuclear energy and </li></ul><ul><li>Electrical energy. </li></ul>
  6. 6. Forms of Kinetic Energy <ul><li>Radiant Energy- is electromagnetic energy that travels in transverse waves. </li></ul><ul><li>Thermal Energy- or heat, is the vibration and movements of atoms and molecules within substances. </li></ul><ul><li>Motion Energy- is energy stored in the movements of objects. </li></ul><ul><li>Sound Energy- the movement of energy through substances in longitudinal waves. </li></ul>
  7. 7. Energy Sources <ul><li>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. </li></ul><ul><li>Nonrenewable Energy- </li></ul><ul><li>Renewable Energy- </li></ul>
  8. 8. Renewable Energy <ul><li>Sources can be replenished in a short period of time. The five renewable sources most used are: </li></ul><ul><li>Biomass- including wood and wood waste, municipal solid waste, landfill gas, and biogas, ethanol and biodiesel. </li></ul><ul><li>Water (hydropower) </li></ul><ul><li>Geothermal Wind </li></ul><ul><li>Wind Solar </li></ul><ul><li>Solar </li></ul>
  9. 9. Nonrenewable Energy <ul><li>The 4 nonrenewable energy sources used most often are: </li></ul><ul><li>Oil and Petroleum products- gasoline, diesel fuel, and propane </li></ul><ul><li>Natural gas </li></ul><ul><li>Uraniam (Nuclear Energy) </li></ul>
  10. 10. Energy Transformation <ul><li>Examples- </li></ul><ul><li>Human body- like a machine and fuel for your machine is food. </li></ul><ul><li>Cars- gas is the fuel. </li></ul>
  11. 11. Questions? How many types of energy are there? A: two B: five C: one D: Answer not above
  12. 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
