Unit: Electric charge and electric force


Possible mastery points
In this lesson, we'll review protons and electrons and start discussing the properties of electric charge, including how charge is quantized.
In this lesson, we'll learn about the law of conservation of charge, insulators and conductors, and how charge is transferred.
In this lesson, we'll learn how Coulomb's law relates the electric force to charge and separation distance. We'll also compare the electric force and gravitational force.
