What computational technique models physical movements by solving Newton's laws for every particle in a molecular system?
Answer
Molecular Dynamics (MD)
Molecular Dynamics (MD) is the specific computational technique employed to model the physical movements of atoms and molecules within a system. This modeling is achieved by numerically solving Newton's laws of motion, which dictates the forces acting upon each individual particle based on its current position relative to all other particles in the system. Unlike static methods that provide only a single snapshot, MD generates a time-dependent trajectory, effectively creating a 'movie' that shows the dynamic behavior critical for understanding drug interactions within the complex, shifting environment of biological machinery.
