  1. 1. a physical quantity expressing the amount of matter in a body. It is a measure of a body's resistance to changes in velocity (inertial mass) and also of the force experienced in a gravitational field (gravitational mass): according to the theory of relativity, inertial and gravitational masses are equal
  2. 5. a push or a pull
  3. 6. a measure of this capacity, expressed as the work that it does in changing to some specified reference state. It is measured in joules (SI units)
  4. 8. the force of attraction that moves or tends to move bodies towards the center of a celestial body, such as the earth or moon
  5. 10. a region containing no matter; free space
  6. 11. a device that diverges or converges a beam of electromagnetic radiation, sound, or particles
  7. 15. the energy of a body or system as a result of its position in an electric, magnetic, or gravitational field. It is measured in joules (SI units), electronvolts, ergs, etc
  8. 16. the energy of motion of a body
  9. 18. the process by which masses of relatively warm air are raised into the atmosphere, often cooling and forming clouds, with compensatory downward movements of cooler air
  10. 20. a measure of the rate of motion of a body expressed as the rate of change of its position in a particular direction with time. It is measured in metres per second, miles per hour, etc
  11. 23. the tendency of a body to preserve its state of rest or uniform motion unless acted upon by an external force
Down
  1. 2. this entity as a source of nuclear energy
  2. 3. the attribute of matter by which it responds to electromagnetic forces responsible for all electrical phenomena, existing in two forms to which the signs negative and positive are arbitrarily assigned
  3. 4. any device for converting mechanical energy into electrical energy by electromagnetic induction, esp a large one as in a power station
  4. 7. the number of times that a periodic function or vibration repeats itself in a specified time, often 1 second. It is usually measured in hertz
  5. 9. the rate of increase of speed or the rate of change of velocity
  6. 12. a resistance encountered when one body moves relative to another body with which it is in contact
  7. 13. a measure of the compactness of a substance, expressed as its mass per unit volume. It is measured in kilograms per cubic metre or pounds per cubic foot
  8. 14. an electronic device used to increase the strength of the signal fed into it
  9. 17. a substance, body, or system that conducts electricity, heat, etc
  10. 19. a flow of electric charge through a conductor
  11. 21. a source of high-intensity optical, infrared, or ultraviolet radiation produced as a result of stimulated emission maintained within a solid, liquid, or gaseous medium. The photons involved in the emission process all have the same energy and phase so that the laser beam is monochromatic and coherent, allowing it to be brought to a fine focus
  12. 22. substance that occupies space and has mass, as distinguished from substance that is mental, spiritual, etc
