  1. Energy Forms

  2. What is Energy? • Energy is the ability to do work • It allows us to change or move matter • We have learned to utilize energy to make life more comfortable and efficient • Energy occurs in many forms

  3. Two Main Groups • Energy can be divided into two main groups: • KINETIC: energy of motion • Motion of waves, molecules, substances, and objects • Radiant, Thermal, Mechanical, Sound, Solar • POTENTIAL: stored energy • Think of it as the “potential” for active energy • Examples include: Chemical, Electrical, Gravitational, Nuclear

  4. Types of KINETIC Energy

  5. Thermal Energy • Thermal = Heat • As molecules in a substance move more quickly, they produce heat and thermal energy is increased • Geothermal Energy- heat energy from the inside the Earth • Geo = Earth

  6. Examples of Thermal Energy

  7. Radiant Energy • Travels in waves • Includes light, x-rays, gamma rays, and radio waves • Also called electromagnetic • Solar energy is a special type of radiant energy that combines heat and light to warm the Earth

  8. Examples of Radiant Energy

  9. Mechanical Energy • Energy produced by moving parts or objects • Machines • Your body • The faster the motion the greater the energy • Think of a car crash

  10. Examples of Mechanical Energy

  11. Types of POTENTIALEnergy

  12. Chemical Energy • Stored in the bonds of atoms and molecules • Energy released from chemical reactions • Is converted into other forms of energy when bonds are broken or combined • Biomass- is stored chemical energy that we get from living things • Bio = living things • Use coal to create fuel

  13. Examples of Chemical Energy

  14. Electrical Energy • Energy created by the movement of charged electrons • Often travel through wires or circuits • Usually converted into other forms of energy

  15. Examples of Electrical Energy

  16. Nuclear Energy • Energy stored in the “nucleus” of atoms • Two processes to access this energy: • NUCLEAR FISSION: splitting one large nucleus into two smaller ones • NUCLEAR FUSION: combining two smaller nuclei into one larger one

  17. Examples of Nuclear Energy

  18. Energy Transformations • Occur when one form of energy is “transformed” or converted into another more useful form • For example: • Electrical Energy Light and Thermal energy
