Thank you for your reply.
Yes something like that but a bit more bouncing back (a bit against of Third Law of Force Physics 
)
I use Nextjs and I haven’t been able yet to import Havok plugin (I’ve read
RaananW’s solution for Vite but I could find something similar for Nextjs - trying to load the plugin from a location that doesn’t exist)
So in my project I’m using cannon.js (since I wasn’t able to fix the error with nextjs + havok plugin) and I moving the spheres using addInPlace.
But I see fromm https://playground.babylonjs.com/#MKR6NF#1 that using addInPlace doesn’t work for Havok Physics? I will ask for a bit of help integrating Havok plugin in Nextjs and try your approach with applyForce
