In the application of the principle of virtual work it is often convenient to obtain virtual displacements from the velocities of the system. For the n particle system, let the velocity of each particle P i be V i, then the virtual displacement δr i can also be written in the form [2] = = ˙, =, …,.
D'Alembert's principle generalizes the principle of virtual work from static to dynamical systems by introducing forces of inertia which, when added to the applied forces in a system, result in dynamic equilibrium. [1] [2] D'Alembert's principle can be applied in cases of kinematic constraints that depend on velocities.
Virtual Villagers is a series of village simulator video games created and developed by Last Day of Work, an independent video game developer and publisher. Each game contains puzzles the player must complete to uncover the ethnic and cultural backgrounds surrounding fictional Polynesian island called Isola (EE-zoh-la).
In analytical mechanics, a branch of applied mathematics and physics, a virtual displacement (or infinitesimal variation) shows how the mechanical system's trajectory can hypothetically (hence the term virtual) deviate very slightly from the actual trajectory of the system without violating the system's constraints.

Classical mechanics is the branch of physics used to describe the motion of macroscopic objects. [1] It is the most familiar of the theories of physics. The concepts it covers, such as mass, acceleration, and force, are commonly used and known. [2]

Mechanics (from Ancient Greek μηχανική (mēkhanikḗ) 'of machines') [1] [2] is the area of physics concerned with the relationships between force, matter, and motion among physical objects. [3] Forces applied to objects may result in displacements, which are changes of an object's position relative to its environment.
