Identify and explain the three different ways that charge is built up on an object.

There are three ways to charge an object: friction, conduction and induction. Friction involves rubbing on material with another, resulting in electrons moving from one surface to another. ... Friction is useful for charging insulators, which are materials that aren't good conductors.
