# Bond graph

A bond graph is a graphical representation of a physical dynamic system. [1]

## Angular displacement

Angular displacement of a body is the angle in radians (degrees, revolutions) through which a point revolves around a centre or line has been rotated in a specified sense about a specified axis.

## Angular momentum

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational equivalent of linear momentum.

## Block diagram

A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks.

## Differential equation

A differential equation is a mathematical equation that relates some function with its derivatives.

## Directed graph

In mathematics, and more specifically in graph theory, a directed graph (or digraph) is a graph that is a set of vertices connected by edges, where the edges have a direction associated with them.

## Dynamical system

In mathematics, a dynamical system is a system in which a function describes the time dependence of a point in a geometrical space.

## Electric charge

Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.

## Electric current

An electric current is a flow of electric charge.

## Energy

In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.

The farad (symbol: F) is the SI derived unit of electrical capacitance, the ability of a body to store an electrical charge.

In circuit theory, flux linkage is a property of a two-terminal element.

## Force

In physics, a force is any interaction that, when unopposed, will change the motion of an object.

## Graph (discrete mathematics)

In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".

## Gyrator

A gyrator is a passive, linear, lossless, two-port electrical network element proposed in 1948 by Bernard D. H. Tellegen as a hypothetical fifth linear element after the resistor, capacitor, inductor and ideal transformer.

## Henry (unit)

The henry (symbol: H) is the SI derived unit of electrical inductance.

## Henry Paynter

Henry M. Paynter (August 11, 1923 – June 14, 2002) was an American scientist, best known as the inventor of bond graphs.

## Hooke's law

Hooke's law is a principle of physics that states that the force needed to extend or compress a spring by some distance scales linearly with respect to that distance.

## Hybrid bond graph

A hybrid bond graph is a graphical description of a physical dynamic system with discontinuities (i.e., a hybrid dynamical system).

## Lever

A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum.

## Mass

Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied.

## Moment of inertia

The moment of inertia, otherwise known as the angular mass or rotational inertia, of a rigid body is a tensor that determines the torque needed for a desired angular acceleration about a rotational axis; similar to how mass determines the force needed for a desired acceleration.

## Momentum

In Newtonian mechanics, linear momentum, translational momentum, or simply momentum (pl. momenta) is the product of the mass and velocity of an object.

## Ohm

The ohm (symbol: Ω) is the SI derived unit of electrical resistance, named after German physicist Georg Simon Ohm.

## Ohm's law

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

## Power (physics)

In physics, power is the rate of doing work, the amount of energy transferred per unit time.

## Pressure

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

## Signal-flow graph

A signal-flow graph or signal-flowgraph (SFG), invented by Claude Shannon, but often called a Mason graph after Samuel Jefferson Mason who coined the term, is a specialized flow graph, a directed graph in which nodes represent system variables, and branches (edges, arcs, or arrows) represent functional connections between pairs of nodes.

## Simcenter Amesim

Simcenter Amesim is a commercial simulation software for the modeling and analysis of multi-domain systems.

## State space

In the theory of discrete dynamical systems, a state space is the set of all possible configurations of a system.

## State variable

A state variable is one of the set of variables that are used to describe the mathematical "state" of a dynamical system.

## State-space representation

In control engineering, a state-space representation is a mathematical model of a physical system as a set of input, output and state variables related by first-order differential equations or difference equations.

## Time derivative

A time derivative is a derivative of a function with respect to time, usually interpreted as the rate of change of the value of the function.

## Transformer

A transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

## Velocity

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.

## Voltage

Voltage, electric potential difference, electric pressure or electric tension (formally denoted or, but more often simply as V or U, for instance in the context of Ohm's or Kirchhoff's circuit laws) is the difference in electric potential between two points.

## Volume

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains.

## 20-sim

20-sim is commercial modeling and simulation program for multidomain dynamic systems, which is developed by Controllab.
