Across
- 2. The flow of electric charge through a conductor. Energy can be transferred from one place to another and from one form to another by electricity.
- 5. Energy can be transferred from one object to another by a force (by the objects pushing or pulling on each other). A force can also transfer energy from one form to another.
- 8. Energy that is stored in an object's temperature. Heat.
- 10. The ability to make things happen. More advanced definition: The ability to do work.
- 12. Energy that is stored and can be used when needed. Energy can be stored in chemicals (food, batteries), height (gravitational), elastic stretching, etc.
Down
- 1. Energy that is stored in the height of objects. Gravity is the force that pulls things down to Earth. The higher an object, the more gravitational energy it has. Often, gravitational energy (a form of potential energy) is converted to kinetic energy to make things move fast.
- 3. Energy that is stored in the chemical bonds of molecules. This energy is released during chemical reactions.
- 4. A fundamental law in thermodynamics. It states that energy cannot be created or destroyed; it can only change from one form to another.
- 6. The energy of moving objects. Anything in motion has kinetic energy. The faster an object moves, the more kinetic energy it has.
- 7. Energy that is stored and can be used when needed. Energy can be stored in chemicals (food, batteries), height (gravitational), elastic stretching, etc.
- 9. Energy that is stored in the height of objects. Gravity is the force that pulls things down to Earth. The higher an object, the more gravitational energy it has. Often, gravitational energy (a form of potential energy) is converted to kinetic energy to make things move fast.
- 11. Energy that is stored in the stretching or compression of objects.
