Molecular dynamics simulations model atomic motion by integrating Newton's Second Law ($F=ma$) within a three-dimensional Cartesian coordinate system to predict particle trajectories over time based on initial positions, velocities, and interatomic forces derived from specific interaction potentials. This computational approach relies fundamentally on the theory that biological systems operate at temporal scales measured in nanoseconds or femtoseconds rather than macroscopic units like seconds, allowing researchers to observe dynamic behaviors such as protein conformational changes within their native solvent environments without relying solely on static structural representations found in standard textbooks. The domain is theoretical biochemistry and computational physics, where this mechanism serves as the primary formalism for bridging microscopic atomic interactions with observable macroscopic biological functions.
