### Electric Charge

 Terms Induction process of heating electr­ically conductive materials Conductors materials that allow electrons to move separately from their atomic orbits Coulomb SI unit of electric chagre Dipole 2 equal and opposite charges Electric Charge electr­ically charged particles Electrons carries the smallest type of negative charge Field Lines Benjamin Franklin named the positive and negative charges Fundam­ental Charge 1.6 x 10-19 Conductor allows electr­icity to flow through it Insulator electric current does not flow freely Coulomb's Law F = k (q1q2)/r2 (electric force increases as charge increases) k = coulomb's constant (8.99 x 109) (electric force decreases as distance increases) q1 = charge of object 1 q2 = charge of object 2 r = distance of object 1 and 2 from each other Vector Analysis - used when 3 or more objects are involved Particle Proton Electron Neutron Mass 9.1093897 x 10-31 kg 1.6726231 x 10-27 kg 1.6749286 x 10-27 kg Charge + 1.69217733 x 10-19 C - 1.69217733 x 10-19 C none Location in Nucleus nucleus outside nucleus nucleus

### Electric Charge 2

 Electr­ostatic Intera­ction 1. Any charged objects can attract a neutral object 2. Unlike charges attract 3. Like charges repel charges of a particle depends on the sum of its electrical charges 1 C = 6.242 x 1018 Ion atom or group of atoms that bears one or more positive or negative charges Cation more proton, positive ion Anion more electron, negative ion Charging Objects
