There are four primary quantities involved with electricity:
Vectors used in the force method: Forces and fields
Scalars used in the energy method: Potential energy and potential (also called voltage)
We have three main goals to accomplish:
1. Determine these four primary quantities for a discrete or continuous distribution of electrical charges
2. Find one of the primary quantities, given the other three
3. Apply these concepts fo find a related quantity such as acceleration, speed or distance
