Some Notes on Electrostatics
This unit focuses primarily on concepts and very little Math will be involved. Having said that, this unit tends to be a greater challenge than previous topics to many students
In many cases, you will not be able to directly see the static charges, but instead their observable effects
Only negative charges, electrons, can move. Positive charges, protons, stay in place.
A ground is a path or place that can accept or donate a large number of electrons, typically the Earth itself. A ground can be used to turn something neutral OR charge something depending on its use
Like the gravitational field, the strength of the electrostatic field is reduced significantly over small distances. This is because it also follows the inverse square law for forces over distance
