The Potential Energy Shortcut or What is a Conservative Force and Why should you care?

Conservative forces, for example, gravity, the spring force and electric forces matter. They allow us to use the potential energy shortcut.

This principle underlies Kirchhoff's Voltage Law in circuits, where the sum of voltage changes in a loop must be zero, reflecting the conservative nature of electric fields. Similarly, a spring's force is conservative as the potential energy is determined solely by the spring's displacement, allowing us to skip calculus.
