Here's a quick one:
If the generalized force F is not zero,
does the equation
dH/dq = -pdot
become
dH/dq = F- pdot
?
If the generalized force F is not zero,
does the equation
dH/dq = -pdot
become
dH/dq = F- pdot
?
Everything. Hamiltonian dynamics concerns itself with positions and generalized momenta. A generalized force is the derivative of a generalized momentum.dextercioby said:What have generalized forces have to do with the hamiltonian formulation of dynamics ??
Hamilton's Equations of Motion are a set of equations used in classical mechanics to describe the motion of a system of particles. They are named after Irish mathematician and physicist William Rowan Hamilton, who first introduced them in the 19th century.
While Newton's Laws of Motion use forces to describe the motion of a system, Hamilton's Equations use energy and momentum. They are also more general and can be applied to a wider range of systems, including systems with constraints and non-conservative forces.
Hamilton's Equations are important in physics because they provide a powerful mathematical tool for analyzing and predicting the motion of complex systems. They are used in various fields of physics, such as mechanics, electromagnetism, and quantum mechanics.
Hamilton's Equations can be derived from a mathematical principle called the principle of least action. This principle states that the actual path taken by a system between two points is the one that minimizes the action, which is a measure of the system's energy.
In most cases, Hamilton's Equations cannot be solved analytically and require numerical methods to obtain solutions. However, there are some special cases where analytical solutions are possible, such as for simple harmonic motion.
