ELECTRIC CHARGES:
Charge: Basic property of matter, can be positive or negative.
Conservation of Charge: Charge is neither created nor
destroyed, only transferred.
CONDUCTORS AND INSULATORS:
Conductors: Materials allowing the flow of charge (e.g., metals).
Insulators: Materials impeding the flow of charge (e.g., rubber,
plastic).
CHARGING BY INDUCTION AND CONDUCTION:
Induction: Bringing a charged object close to a neutral object, inducing a
charge separation.
Conduction: Charging a neutral object by direct contact with a charged
object.
COULOMB'S LAW:
Coulomb's Law: Describes the electrostatic force between two charged
objects.
F = k*|q1*q2|/r^2: where f is electrostatic force, q1 and q2 are the charges, r
is the distance between them, and k is Coulomb’s constant.
ELECTRIC FIELDS:
Electric Field (E): Region around a charged object where it can exert a force
on another charged object.
E = F/q : Electric field strength is the force experienced per unit positive
charge
