Molecular modeling is primarily a tool for calculating the energy of a given molecular structure. Thus, the first step in designing a molecular modeling investigation is to define the problem as one involving a structure-energy relationship. There are two conceptually different ways of thinking about energy.
Quick Answer. A scientific model is a conceptual, mathematical or physical representation of a real-world phenomenon. A model is generally constructed for an object or process when it is at least partially understood, but difficult to observe directly. Examples include sticks and balls representing molecules, mathematical models of planetary movements or conceptual principles like the ideal gas law.
