Across
  1. 2. A push or pull exerted on an object
  2. 3. the region around a magnet where the magnetic force is exerted
  3. 4. an attractive force that acts between any two objects
  4. 5. A place or object used for comparison to determine if an object is in motion
  5. 7. A simple labeled diagram that shows the forces acting on an object as arrows that indicate the magnitude and direction of the force.
  6. 8. to push away
  7. 9. Friction that opposes motion once the motion has already started
  8. 13. the region of space surrounding a body in which another body experiences a force of gravitational attraction
  9. 14. forces acting on an object that combine and form a net force of zero
  10. 19. opposes the motion of an object when an object moves through a fluid (e.g., gas, liquid)
  11. 21. a region around a charged object where the object's electric force is exerted on other charged objects
  12. 25. A material that allows heat and electricity to pass through it.
  13. 26. A measure of the extra positive or negative particles that an object has.
  14. 28. to pull toward
  15. 29. A measure of the gravitational force exerted on an object.
  16. 30. Energy caused by the movement of electrons.
  17. 32. not moving; not changing
  18. 33. the tendency of an object to resist a change in its motion
Down
  1. 1. Kinetic or potential energy associated with the motion or position of an object
  2. 3. the attraction or repulsion between magnetic poles
  3. 6. lines that map out the invisible magnetic field around a magnet
  4. 10. The overall force on an object when all the individual forces acting on it are added together
  5. 11. The force of attraction or repulsion of magnetic materials
  6. 12. size or numerical value
  7. 15. A force that one charge exerts on another. When the charges are the same sign, they repel; when the charges are opposite, they attract.
  8. 16. The distance an object travels per unit of time
  9. 17. A form of energy caused by the movement of electrons.
  10. 18. a device that converts electrical energy into mechanical energy
  11. 20. Change in velocity divided by the time it takes for the change to occur; the net force is greater than zero
  12. 22. A machine that converts mechanical energy into electrical energy
  13. 23. An object's change in position relative to a reference point.
  14. 24. temporary magnet that loses its magnetism when the electric current is turned off
  15. 27. one of the two ends of a magnet where the magnetism seems to be concentrated
  16. 31. the amount of matter in an object
