Coulomb's Law:It describes the force between two charged objects and is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Conservation of Charge: The principle that states that electric charge cannot be created or destroyed, only transferred from one object to another.
Conductors and Insulators: Conductors are materials that allow electric charges to flow easily, while insulators are materials that resist the flow of electric charges.
