  1. 1. Energy - energy due to motion
  2. 4. Energy - energy carried by sound waves
  3. 5. of Conservation of Energy - a scientific law that states that energy can be transformed from one form to another, but it cannot be created or destroyed
  4. 6. Energy - energy stored in chemical bonds, like a hidden power, waiting to be used, like batteries, food we eat, wood or coal.
  5. 9. - the transfer of thermal energy by electromagnetic waves (no contact).
  6. 11. Energy - the sum of the kinetic energy and potential energy of the particles that make up the object
  7. 12. Energy - energy carried by electromagnetic waves
  8. 13. Energy - the sum of the potential energy and kinetic energy in a system
  9. 15. System - a system that exchanges matter or energy with the environment
  10. 16. - the ability to do work/cause change
  11. 18. System - a system that does not exchange matter or energy with the environment

  1. 2. - the transfer of thermal energy by the movement of particles from one part of a material to another. Convection only occurs in fluids (water, air, magma, maple syrup, etc.). Convection cannot occur in solids, because particles in solids cannot flow.
  2. 3. Energy - the energy in an electric current
  3. 7. - the transfer of energy that occurs when a force makes an object move in the direction of the force. Work is only being done while the force is acting on the object.
  4. 8. - the transfer of thermal energy by collisions (direct contact) between particles of matter
  5. 10. Energy - stored energy due to the interaction between objects or particles
  6. 14. Transfer - when energy moves from one object to another without changing form
  7. 17. Transformation - when one form of energy is converted to another form of energy
