Lesson 2: Coulomb's Law

Hook:

Show Gizmo regarding the electric force between charges.
The following gizmo shows the Coulomb force between two charges.  Show a whole bunch of different scenarios and see if the students' can come up with an estimation of Coulomb's law.

Action:

Discuss the past use of gravitational potential energy in previous units (Energy and Momentum).
Make connection to celestial bodies and go over misconceptions of potential energy.

Debrief:

Prompting questions regarding applications and societal implications.  Hand in handout for assessment.
