Energy Test Study Guide 1. What is energy? Energy is the ability to do work or cause change. 2. What is heat energy? Heat energy is the transfer of thermal energy. 3. Complete the sentence: The faster the molecules move, the higher the temperature. 4. What is solar energy? Solar energy is the energy from the Sun, which provides heat and light energy for Earth. 5. What is a solar cell? Solar cells can be used to convert solar energy to electrical energy. 6. What is chemical energy? Chemical energy is energy stored in particles of matter. 7. What are the 3 sources of chemical energy? gy can be found in batteries or food or anything that burns. 8. What is electrical energy? Electrical energy is the energy flowing in an electric circuit. 9. What are the 4 sources of electrical energy? 1) stored chemical energy in batteries 2) solar energy in solar cells 3) hydroelectric power plants 4) coal burning power plants 10. What is mechanical energy? Mechanical energy is the energy due to the motion (kinetic) and position (potential) of an object. 11. What are the 2 types of mechanical energy? potential and kinetic 12. What is potential energy? Mechanical Potential energy is stored energy. Mechanical potential energy is related to the position of an object. Examples: A stretched rubber band has potential energy. Water behind a dam has potential energy because it can fall down the dam. 13. What is kinetic energy? Mechanical Kinetic energy is the energy an object has due to its motion. Mechanical kinetic energy increases as an object moves faster. 14. What is the law of conservation of energy? The Law of Conservation of Energy states that energy cannot be created or destroyed. It may be transformed from one form into another, but the total amount of energy never changes. 15. Most of the energy that we use on Earth originally came from where? the Sun 16. Be able to give examples of how energy is transferred from one form to another. Be able to give examples of energy transfer from potential to kinetic. 17. Review inquiry/process skills.
