I try to create a simulation of the newton's pendulum with the dynamics and I encounter problems! I've created five spheres with a gravity field and a nail constraint! When I launch my simulation, the spheres collide themselves correctly but not as the same way as a Newton's pendulum! All the spheres are moving how you can see below in my simulation! With a Newton's pendulum, just the first and the last sphere move! Here is my test: http://homepage.hispeed.ch/cireb/Video/testnewton.mov What I want to do: http://www.ap.stmarys.ca/demos/conte...endulum_HR.wmv Please help me! Thanks!

I've tried the uniform field and the result is a little bit better! But unfortunately the middle spheres are still moving!

I think yes!
Here is my project file: http://homepage.hispeed.ch/cireb/Newton.mb

If you can see it, it would be very nice of you!

Thanks!
