Molecular mechanics, also known as molecular dynamics, is a powerful simulation technique that has greatly impacted the field of chemistry. It involves the study of the movement and behavior of molecules to predict their properties and interactions with other molecules. However, there are other terms that can be used interchangeably with molecular mechanics, including computational chemistry, molecular modeling, and quantum mechanics. Computational chemistry uses advanced computer algorithms to simulate the behavior and structure of molecules, while molecular modeling focuses on creating three-dimensional models of molecules to better understand their properties. Quantum mechanics is a more advanced field of study that utilizes high-level mathematical equations to study the behavior and interactions of subatomic particles.
