- 3. a form of energy caused by the movement of electrons
- 5. an attractive force that acts between any two objects
- 7. a region around a charged object where the object’s electric force is exerted on other charged objects
- 10. energy caused by the movement of electrons
- 13. the force of attraction or repulsion of magnetic materials
- 14. the attraction or repulsion between magnetic poles
- 16. a force that one charge exerts on another – when the charges are the same sign, they repel; when the charges are opposite, they attract
