molecular dynamics simulates time evolution of a molecular system using a chosen interaction model. Simulated pathways and state populations require adequate sampling and validation against measured observables; a plausible trajectory alone does not establish a biological mechanism.

Molecular dynamics (MD) is a computational simulation technique used to study the physical movements of atoms and molecules over time. By applying classical mechanics, scientists can model the interactions and trajectories of particles to understand the dynamic behavior of systems at the molecular level. Key aspects of molecular dynamics include: 1. **Force Fields**: MD simulations rely on force fields, which are mathematical models that describe the potential energy of a system based on the positions of its atoms.
