| friction | way to create a charge by rubbing objects together |
| contact | way to create a charge by touching a charged object to a neutral object |
| induction | way to create a charge by bringing a charged object near a neutral object |
| proton | positively charged particle of an atom |
| electron | only particle of an atom that can be gained or lost |
| neutron | neutral particle of an atom |
| electric force | force of attraction or repulsion between objects due to charge |
