  1. 2. German astronomer who figured out the relationship among a planet's orbital period and its average distance from the sun
  2. 5. when an object experiences changing acceleration
  3. 8. components wired in ___ share voltage and have the same current
  4. 10. how quickly an object's speed or direction changes
  5. 13. transfer of energy between two objects at different temperatures
  6. 16. -273.15 degrees Celsius; temperature at which all particle motion would completely stop
  7. 18. state in which the net force on an object is zero (zero or constant velocity); or, in thermodynamics, when two objects in contact have the same temperature
  8. 19. in a vacuum, the ___ is the same for all observers no matter what they're doing
  9. 21. a measurement that has both magnitude and direction
  10. 22. final position compared to initial position; example = 18 meters south
  11. 25. motion of an object when only gravity acts on it; causes object to accelerate at -9.80 m/s^2 near Earth's surface
  12. 26. measure of energy required to make a substance undergo a phase change
  13. 28. tendency of an object to maintain its current state of motion
  14. 29. a transfer of energy; product of force and distance
Down
  1. 1. how difficult it is to change a substance's temperature; thermal inertia
  2. 3. to calculate the work done on or by a gas, multiply the ___ by the change in volume
  3. 4. rate at which charges pass through a certain area; measured in amperes
  4. 6. rate of change of position
  5. 7. action exerted on an object that may change the object's state of motion
  6. 8. measure of how stiff a stretchable/compressible object is
  7. 9. electric ___ is a measure of how much work has to be done to move a charge relative to the magnitude of the charge
  8. 11. thermodynamic process marked by rapid compression/expansion of gas and no heat transfer
  9. 12. rate at which work is done or energy is transformed
  10. 14. measure of a substance's particles' average kinetic energy
  11. 15. measured in ohms, it's the opposition to electric current

  13. 20. the coefficient of friction is the ratio of the amount of frictional force to the ___ force for two solid objects in contact with each other
  14. 23. thermodynamic process that takes place without a temperature change
  15. 24. product of mass and velocity; is conserved when 2 objects collide
  16. 27. measure of heaviness, or how much force gravity is exerting on an object
