Across
- 3. Energy Radiant energy from the sun that can be captured and converted into electricity, such as with solar panels, or used for solar thermal energy. It is a renewable energy source.
- 4. Energy The energy an object possesses due to its motion.
- 7. Potential Energy Potential energy that depends on an object's height within a gravitational field.
- 9. Energy The sum of the kinetic and potential energy associated with the motion and position of an object.
- 10. Energy Energy stored in the nucleus of an atom that is released when the nuclei are combined (fusion) or split apart (fission). Nuclear power plants use fission of uranium atoms to generate electricity.
- 11. Energy Stored energy resulting from the position or configuration of a system.
- 12. Energy This term is not a standard, distinct form of energy in physics in the way the other terms are. Energy is typically relative and measured as a change or transfer (e.g., in joules).
- 14. Energy Heat from within the Earth that can be used to generate electricity or for heating. The decay of uranium deep inside the Earth is responsible for most of this heat.
- 16. Energy Also known as radiant energy or electromagnetic radiation, this energy travels in waves and spans a spectrum from radio waves to gamma rays. Visible light and heat from the sun are common examples.
Down
- 1. Energy Energy generated by gravity forcing water down through a hydroelectric turbine to produce electricity. It is considered a renewable energy source.
- 2. Energy Energy that results from the flow of charged particles, such as electrons, through a conductor. Lightning and the power used in homes are examples.
- 5. Energy Resources Natural resources that exist in a fixed amount and cannot be replenished on a human timescale. Examples include fossil fuels (oil, coal, and natural gas) and uranium for nuclear power.
- 6. Energy Energy from organic materials like wood, agricultural crops and waste, and manure, which contain stored chemical energy from the sun. This material can be burned to produce heat or electricity.
- 8. Potential Energy The energy stored in an elastic object (like a spring or rubber band) when it is stretched or compressed.
- 13. Energy The total kinetic and potential energy of all the microscopic particles (atoms and molecules) within an object; essentially, heat energy.
- 15. Energy Energy stored in the bonds of atoms and molecules that is released during chemical reactions.
