Hi folks,
Kay found that interesting page that I already knew before:
http://www.myphysicslab.com/
On the site the Lagrangian is used for some of the simulations and is
described very well. We could take the description there as kind of
orientation for the concepts in our classical mechanics module which is
the first simulation module I'd like to develop. I think I will create a
diagram or so for that as I already started together with Tim last
thursday, now complete with the information from myphysicslab which
solved most problems we were not sure about.
Things to note:
- We may need a CAS for the partial derivative of the Lagrangian and
other stuff whilst ODE solving must be done numerically (Runge-Kutta)
- Spring forces can also be included in the Lagrangian, only
non-conservative forces (forces which make the system lose mechanical
energy such as friction) must be treated as an extra influx inside the
ODE
Have fun!
