And what evidence is there for this assertion? Can you show this by pre and
post-testing on either the FCI or FMCE? I truly doubt it.
Conservation of momentum is weakly connected to forces in the minds of
students. Indeed getting them to make the connection is fairly difficult.
There are some excellent direct demonstrations of the effect of forces in
the Interactive Lecture Demonstrations by Thornton et al that work fairly
well and show high gain on the FMCE. Can you demonstrate similar gain by
using conservation of momentum labs?
If you can get similar gain then by all means publish the results so that
others can use the same method.
