Charging by conduction
Charging an object by allowing it to come into contact with an object that already has an electrical charge
Charging by induction

Conductors
materials that allow electric charges to flow through them easily
Coulomb
unit of charge
Electric force
the attraction or repulsion between electric charges
Electrons
negatively charged particles
Force
push or pull that gives energy to an object
Grounding
the transfer of excess charge through a conductor to Earth
Insulators
materials that prevent electric charges from flowing through them easily
Laws of static charge
Physical laws that state that like charges repel, opposite charges attract, and neutral objects and charged objects attract each other.
Static charge
Build up of electrons on an object
Van de Graaff generator
