Vocabulary
conduction - the transfer of charge by direct contact. conductor - a material across which electrons can easily travel. charging by friction - the transfer of electrons by two objects being rubbed together. electrostatic force (FE) - one of the four fundamental forces of the universe; the attraction and repulsion of particles based on their electrical charges; is equal to Coulomb’s constant times the magnitude of two charges divided by the distance between the charges, squared. induction - charging a neutral object by bringing a charged object close to but not touching the object.
