The Google Summer of Code organization applications open next week. I
would appreciate help updating the GSoC ideas page
https://github.com/sympy/sympy/wiki/GSoC-Ideas. Please remove any

Another thing is that this year they are changing the

Now all clear to me, thanks!

Peter,
Yes, the velocity constraints work the same way. There are reaction forces
that constrain the velocities.

Dear Jason,
Thanks!
If I understood correctly, if I use velocity constraints, I do not use the
minimal number of generalized coordinates, hence these reaction forces and
'virtual' speeds appear in my force term of the equations of motion. As
they are normal to the motion of the particle(s), I
Peter,
If you have a particle that is forced to move along a path (typically be a
configuration constraint), then there exists reaction forces normal to the
path that keep it on the path. These forces are not present in the
equations of motion when they are formed with minimal coordinates. But
Thanks! Would I also set the 'reaction forces' appearing in the force term
equal to zero?
As per my understanding of mechanics, they also should have no influence on
the equations of motion (?)

The virtual speeds will appear in the force equations, but you then just
set them to zero because they are fictitious. You force equation should
then be correct.

When I use a velocity constraint to force a particle not to move in a
certain direction, there must be a 'reaction force' on the particle.
I use KM.auxiliary_eqs to find reaction forces, which works very well in
general!
However, if I try to find the reaction force due to a velocity
