frictionA method of charging an object by rubbing it against another object; the force that one object exerts on another when the two rub against each other.
conductionA method of charging an object by allowing electrons to flow by direct contact from one object to another object.
inductionA method of charging an object by means of the electric field of another object; the objects have no direct contact.
