- Generalized force
The idea of a Generalized Force is a concept stemming from
Lagrangian mechanics. It is a consequence of the application of generalized coordinatesto a system undergoing acceleration.
When a particle undergoes a
virtual displacementunder the influence of a force the virtual workdone by that force is given by:
and by reversing the order of summation we get
It is from this formulation that the idea of a generalized force stems. The above equation can be written as
is called the generalized force associated with the coordinate .
