  1. 5. motor An electric motor is an electrical machine that converts electrical energy into mechanical energy.
  2. 6. attractive or repulsive force exerted by all charged objects on each other.
  3. 8. a measure of the amount of electrical potential energy an electron flowing in a circuit can gain; measured in volts
  4. 9. a material in which charges can move easily
  5. 13. rapid movement of excess charge from one place to another
  6. 15. surrounds every electric charge and exerts force on other electric charges

  1. 1. an imbalance of electric charges within or on the surface of a material or between materials. The charge remains until it is able to move away by means of an electric current or electrical discharge.
  2. 2. Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
  3. 3. the flow of electric charge, measured in amperes
  4. 4. a measure of how difficult it is for electrons to flow in a material; unit is the ohm.
  5. 7. the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.
  6. 10. closed conducting loop in which electric current can flow continually
  7. 11. a push or pull
  8. 12. a material in which charges do not flow easily because they do not have feel flowing electrons.
  9. 14. An atom or a group of atoms that has an electric charge.
