I need help with how to separate the fragments from the main object.

How to separate the fragments from the main object, I want to make the fragments fly away, but if I set the force operator, the main stone also flies away.
I would be very grateful for your help.

separate the main object in another event, add PhysX switch operator and set it to kinematic

Thank you very much, this helped! Can you also tell me how to add a collision to the orange object so that the debris doesn't pass through it but collides with it.
