Across
  1. 2. A law describing the electrostatic force of interaction between charged particles based on the strength of the charges and the distance between the particles.
  2. 3. A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
  3. 4. The production of electric potential difference across a conductor as the conductor moves through a magnetic field.
  4. 6. An interaction between an object and another object or a field that acts to change the motion of the object.
  5. 11. A material that allows electrons to flow freely from particle to particle.
  6. 13. A force that acts to move objects closer together.
  7. 15. The region of space surrounding a body in which another body experiences a force of gravitational attraction.
  8. 17. A closed loop of conductors through which an electric current can flow.

Down
  1. 1. An attraction related to the relative charge of an object.
