  1. DO NOW Q1. Define Energy? Q2.What is the unit for energy and its symbol?

  2. DO NOW (ANSWERS) Q1. Define Energy? the capacity to do work Q2. What is the unit for energy and its symbol? The unit for energy is joules (J) and the symbol for energy is E

  3. Law of Conservation of Energy Law of Conservation of Energy- Energy can neither be created nor destroyed. Energy is always changing from one kind to another. The total energy of an object never changes. Main Menu Main Menu

  4. Renewable and Nonrenewable Sources Nonrenewable Renewable Main Menu

  5. Types of Energy Kinetic Energy Potential Energy Main Menu

  6. Forms of Energy Chemical Sound Radiant Electrical Mechanical Magnetic Thermal Nuclear Main Menu

  7. Chemical Energy Chemical energy is the energy stored in the bonds of atoms and molecules. This a form of potential energy until the bonds are broken. Fossil fuels and biomass store chemical energy. Products that contain chemical energy include: TNT, baking soda, and a match. Biomass, petroleum, natural gas, propane and coal are examples of stored chemical energy. Forms of Energy

  8. Nuclear Energy Nuclear energy is the energy stored in the nucleus of an atom. Nuclear energy is unusual in that it can give off energy in the form of light or heat, Submarines, power plants, and smoke detectors all use nuclear energy. Nuclear power plants use uranium, a radioactive element, to create electricity. Forms of Energy

  9. Sound Energy Sound energy is the movement of molecules in the air that produces vibrations and sound. Forms of Energy

  10. Mechanical Energy Mechanical energy is the movement of machine parts. Mechanical energy is also the total amount of kinetic and potential energy in a system. Wind-up toys, grandfather clocks, and pogo sticks are examples of mechanical energy. Wind power uses mechanical energy to help create electricity. Potential energy + Kinetic energy = Mechanical energy Next

  11. Magnetic Energy Magnetic energy is the attraction of objects. Magnetic energy is the attraction of objects made of iron. Medical equipment, compass, refrigerator magnets are all examples of magnetic energy. Any type of energy source that uses a generator in the process to make electricity uses magnetic energy. Forms of Energy

  12. Kinetic Energy The greater the mass or velocity of a moving object, the more kinetic energy it has. Kinetic Energy Lab Types of Energy

  13. Potential Energy Potential energy exists whenever an object which has mass has a position within a force field. The most everyday example of this is the position of objects in the earth's gravitational field. Types of Energy Potential Energy Lab
