Electric Potential Energy of 3 Point Charges (16:50)
Struggling to understand electric potential energy in a system of three point charges? In this AP Physics 2 lesson, Mr. P and the Flipping Physics crew walk through a conceptual and mathematical breakdown of how to calculate and interpret the electric potential energy of a three-charge system arranged in an equilateral triangle. Go beyond plug-and-chug—learn how the physics actually works, why signs matter, and how potential energy relates to work and energy transformation. This is the deep dive every physics student needs.
