The coupled oscillator approach is very useful for modelling exoplanet interiors, galaxy cluster mergers and compact binary spirals. In this study, a simplified two-coupled oscillator model to quantify energy dissipation due to linear tidal forces is developed and its implications for cosmic evolution explored. The model incorporated gravitational and tidal interactions and the equations of motion of the system is derived using Lagrangian mechanics with dissipative terms which made it easier to treat tidal dynamics as solvable mechanical systems. The model also predicts dissipation rates for orbits, spins and deformations and links microphysics to macroscale evolution.
