TERM 1 Electrical Charge DEFINITION 1 An excess or deficit of electrons on an object. TERM 2 Electricity DEFINITION 2 A force, more powerful than gravity, that moves objects both toward and away from each other, depending on the charge. TERM 3 Static Electricity DEFINITION 3 A phenomenon caused by the transfer of electrical charge between objects. Often observed as lightning or as sparks produced when walking across a wool rug on a dry, cold day. TERM 4 Positive Electrical Charge DEFINITION 4 A deficiency of electrons on an object. TERM 5 Negative Electrical Charge DEFINITION 5 An excess of electrons on an object. TERM 6 Coulomb's Law DEFINITION 6 An empirically derived rule that states that the magnitude of the electrostatic force between any two objects is proportional to the charges of the two objects, and inversely proportional to the square of the distance between them. TERM 7 Electric Field DEFINITION 7 The force that would be exerted on a positive charge at a position near a charged object. Every charged object is surrounded by an electric field. TERM 8 Magnet DEFINITION 8 Materials that exert a magnetic field on other objects. Magnetite or "lodestone" is a common natural magnet. TERM 9 Magnetic Force DEFINITION 9 The force exerted by magnets on each other. TERM 10 Poles (North and South) DEFINITION 10 The two opposite ends of a magnet, named north and south, that repel a like magnetic pole and attract an unlike magnetic pole.
