  1. 1. The ability to do work.
  2. 3. Increasing (or decreasing) one quantity would have the same effect on another.
  3. 6. Balanced forces. Net force is zero.
  4. 10. An object at rest remains at rest, an object in motion remains at a constant velocity unless acted upon by unbalanced forces
  5. 14. An electric circuit with a single path
  6. 15. The force of attraction or repulsion of magnetic materials
  7. 17. Resistance to change in motion, that only depends on mass.
  8. 19. The combination of all forces acting on an object.
  9. 21. For every action force, there is an equal and opposite reaction force.
  10. 22. A quantity that has only magnitude
  11. 23. sound waves and water waves.
  12. 27. Electromagnetic radiation arranged in the order of its wavelength; a rainbow is a natural spectrum of visible light from the Sun.
  13. 30. A quantity that has both magnitude and direction
  14. 31. A wave that can only propagate through a medium.
  15. 34. Increasing (or decreasing) one quantity would have the opposite effect on another.
  16. 36. A measure of the extra positive or negative particles that an object has.
  17. 37. The acceleration of an object depends on the mass of the object and the amount of force applied. Force = mass x acceleration
  18. 41. A property of matter stating is can be have a positive or negative charge.

  1. 2. A form of energy that can move through the vacuum of space. Examples - light, heat, microwaves, radio waves, x-rays.
  2. 4. It states that energy cannot be created or destroyed, it can only change form.
  3. 5. The force that opposes motion between two surface that are touching
  4. 6. The continuous flow of electric charges through a material
  5. 7. The rate at which an object changes position (like speed), but also includes direction of motion.
  6. 8. When an object changes position with respect to a reference point.
  7. 9. A result of a force moving an object a certain distance.
  8. 11. Energy due to the motion of an object.
  9. 12. A circuit that contains more than one path for current flow.
  10. 13. The study of matter and energy and the interactions between the two through forces and motion.
  11. 16. Stored energy
  12. 18. The DISTANCE between identical points of a wave (such from one crest to another)
  13. 20. How many wave peaks pass a certain point per given time.
  14. 24. A push or pull exerted on an object in an effort to change that object's velocity.
  15. 25. The rate at which an object changes velocity.
  16. 26. The force between electrically charged objects.
  17. 28. The region of force around a charged object.
  18. 29. How fast work is done.
  19. 32. A force of attraction between objects that is due to their masses.
  20. 33. The rate at which an object changes its position.
  21. 35. Voltage = Current x Resistance
  22. 38. A measure of the force of gravity on an object
  23. 39. (of waves) The TIME between two wave crests or troughs.
  24. 40. The amount of matter in an object.
