Using Graphs to Answer "Why" Questions of Electric Potential Energy
Why is the electric potential energy of unlike charges negative? Why does it decrease as they get closer? In this Flipping Physics lesson, we graph electric potential energy vs. distance for a two-point charge system and use the shape of...
