  1. 4. vibration about an equilibrium position in which a restoring force is proportional to the displacement from equilibrium
  2. 6. the distance between two adjacent similar points of a wave, such as from crest to crest or from trough to trough
  3. 8. the lowest point below the equilibrium position
  4. 10. Friction retards the motion of the vibrating mass, and the mass-spring system eventually comes to rest which is what type of effect?
  5. 12. Measurements show that the restoring force is directly proportional to the displacement of the _______.
  6. 13. As the pendulum swings past its equilibrium position, the kinetic energy decreases while the gravitational potential energy _______.
  7. 17. a point in a standing wave, halfway between two nodes, at which the largest displacement occurs
  8. 18. Displacements of matter where two waves can occupy the same space at the same time which causes a combination of two overlapping waves is called what?
  9. 21. a superposition of two or more waves in which individual displacements on the same side of the equilibrium position are added together to form the resultant wave
  10. 23. Ripple waves start with a _______ which causes water on the surface near that point to move, which in turn causes points farther away to move.
  11. 25. One thing that affects a period for a pendulum is the change in the free-fall acceleration but there is another factor that affects the period by changing the what of the pendulum?
  12. 28. The spring force and acceleration (increase/ decrease) as the mass moves toward the equilibrium position, and the speed of the mass increases.

  1. 1. the maximum displacement from equilibrium
  2. 2. a wave pattern that results when two waves of the same frequency, wavelength, and amplitude travel in opposite directions and interfere with each other
  3. 3. a superposition of two or more waves in which individual displacements on opposite sides of the equilibrium position are added together to form the resultant wave

  14. 24. When force is greater, acceleration is greater and the amount of _____ required for a single cycle should decrease.
  15. 26. a point in a standing wave that maintains zero displacement
  16. 27. the time that is takes a complete cycle to occur
