Coulomb's constant

Definition

Coulomb's constant, denoted as k, is a proportionality constant that relates the electrostatic force between two charged objects to their charges and the distance between them.

Analogy

Think of Coulomb's constant as the "glue" that holds together the electrostatic force equation. Just like how glue keeps things together, Coulomb's constant keeps the relationship between charge and distance in balance.
