- 24. the rate at which someone or something is able to move or operate.
- 25. a minute portion of matter
- 29. energy energy stored in the bonds of atoms and molecules
- 30. energy the power an atom's charged particles have to cause an action or move an object
- 32. he number of things—which could be people, animals, plants, or objects—in a certain area
- 34. theory the theory that all matter is made up of tiny indivisible particles
- 35. energy energy which a body possesses by virtue of being in motion.
- 36. the movement caused within a fluid by the tendency of hotter
- 38. the substance of which a physical object is composed
- 40. the flow of electrical power or charge.
- 41. energy the energy possessed by a body by virtue of its position relative to others
Down
- 1. energy the energy of either an object in motion or the energy that is stored in objects by their position
- 3. strength or energy as an attribute of physical action or movement.
- 5. the central and most important part of an object, movement, or group, forming the basis for its activity and growth
- 6. energy is the energy contained within a system that is responsible for its temperature.
- 7. the resistance that one surface or object encounters when moving over another
- 8. light the segment of the electromagnetic spectrum that the human eye can view
- 9. just greater than that of the red end of the visible light spectrum but less than that of microwaves
- 10. Effect a process that occurs when gases in Earth's atmosphere trap the Sun's heat.
- 12. a particle of matter that uniquely defines a chemical element
- 14. force the sum of all the forces acting on an object
- 16. speed of motion, action, or operation
- 17. the SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere.
- 20. the ability to do something or act in a particular way, especially as a faculty or quality
- 21. the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature
- 23. shorter wavelengths than visible light.
- 26. budge represents the balance between the amount of energy incoming to Earth from the Sun
- 27. a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.
- 28. energy that comes from a source and travels through space at the speed of light.
- 31. The capacity or power to do work
- 33. energy the energy in the nucleus, or core, of an atom.
