Analytical mechanics

In theoretical physics and mathematical physics, analytical mechanics, or theoretical mechanics is a collection of closely related formulations of classical mechanics.

See Generalized forces and Analytical mechanics

D'Alembert's principle

D'Alembert's principle, also known as the Lagrange–d'Alembert principle, is a statement of the fundamental classical laws of motion. Generalized forces and D'Alembert's principle are classical mechanics and Lagrangian mechanics.

See Generalized forces and D'Alembert's principle

Degrees of freedom (physics and chemistry)

In physics and chemistry, a degree of freedom is an independent physical parameter in the formal description of the state of a physical system.

See Generalized forces and Degrees of freedom (physics and chemistry)

Fictitious force

A fictitious force is a force that appears to act on a mass whose motion is described using a non-inertial frame of reference, such as a linearly accelerating or rotating reference frame. Generalized forces and fictitious force are classical mechanics.

See Generalized forces and Fictitious force

Force

A force is an influence that can cause an object to change its velocity, i.e., to accelerate, meaning a change in speed or direction, unless counterbalanced by other forces. Generalized forces and force are classical mechanics.

See Generalized forces and Force

Generalized coordinates

In analytical mechanics, generalized coordinates are a set of parameters used to represent the state of a system in a configuration space. Generalized forces and generalized coordinates are Lagrangian mechanics and mechanical quantities.

See Generalized forces and Generalized coordinates

Lagrangian mechanics

In physics, Lagrangian mechanics is a formulation of classical mechanics founded on the stationary-action principle (also known as the principle of least action). Generalized forces and Lagrangian mechanics are classical mechanics.

See Generalized forces and Lagrangian mechanics

Physical system

A physical system is a collection of physical objects under study.

See Generalized forces and Physical system

Virtual displacement

In analytical mechanics, a branch of applied mathematics and physics, a virtual displacement (or infinitesimal variation) \delta \gamma shows how the mechanical system's trajectory can hypothetically (hence the term virtual) deviate very slightly from the actual trajectory \gamma of the system without violating the system's constraints. Generalized forces and virtual displacement are classical mechanics and Lagrangian mechanics.

See Generalized forces and Virtual displacement

Virtual work

In mechanics, virtual work arises in the application of the principle of least action to the study of forces and movement of a mechanical system.
