Energy Crossword

4. Heat the amount of heat needed to raise 1 kg of a material by 1°C; different for different substances
7. Energy Equation Q = mcΔT (heat equals mass × specific heat × change in temperature)
9. the amount of matter in an object; measured in kilograms (kg)
14. energy cannot be created or destroyed, only changed into different forms
15. a push or pull measured in Newtons (N)
16. the transfer of energy between objects; measured in Joules
17. energy produced by vibrating objects; used for communication
20. the ability to cause change; measured in Joules (J)
23. total amount of kinetic and potential energy in a system
24. heat transfer through direct contact of particles; occurs best in solids
25. materials that allow heat to flow easily (ex: metals, skin)
26. energy released from the nucleus of an atom
27. a measure of the average kinetic energy of particles in an object
28. energy stored in objects above Earth’s surface; GPE = mgh (HAM in your notes)

1. stored energy
2. energy stored in chemical bonds of compounds
3. energy from light sources such as the sun or lightbulbs; also called solar or light energy
5. the transfer of energy when a force causes an object to move; W = Fd
6. how far an object moves; measured in meters (m)
8. materials that resist heat flow (ex: air, wood, Styrofoam, plastic)
10. heat transfer through fluid movement caused by temperature and density differences; occurs in liquids and gases
11. the total kinetic + potential energy of particles in an object; increases with mass and temperature
12. the speed of an object in a given direction; measured in m/s
13. energy that travels in electrical and magnetic waves and can move through space
18. energy from outlets or power plants that powers electrical devices
19. energy of motion; calculated using KE = ½mv²
21. the rate at which work is done; measured in Watts; P = W/t
22. heat transfer through electromagnetic waves; does not require matter
