The mechanical equivalences of L-C-R components of an oscillating crystal can be understood by comparing an electrical LC circuit with a mechanical spring-mass-damper system: * Inductor (L) ↔ Mass (m): Inductor stores energy in its magnetic field, analogous to mass storing kinetic energy. * Capacitor (C) ↔ Spring (k): Capacitor stores energy in its electric field, analogous to the spring storing potential energy. * Resistor (R) ↔ Damper (b): Resistor dissipates energy as heat, analogous to a damper dissipating __________ _________ ___ _______ ______.
