The document discusses different types of energy including potential energy, kinetic energy, and various forms of each. It defines energy and explains that there are two main categories: potential and kinetic. Potential energy sources include chemical, mechanical, nuclear, and electrical, while kinetic includes radiant, thermal, and motion. The document also covers renewable vs. nonrenewable energy sources and gives examples of energy transformation.

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. http://www.youtube.com/watch?v=kw_4Loo1HR4 Video

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.
