Hi all!

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: https://homepage.hispeed.ch/cireb/Video/testnewton.mov

What I want to do: https://www.ap.stmarys.ca/demos/conte...endulum_HR.wmv

Please help me!

Thanks!
