How to make model fling

Hello! Im creating a simple game for me and my friends, and I need model to fling.
What I mean by fling is to model realistically fall from a platform.
I have not a little amount of parts and unions in the model.
That`s all from me, any answer would be appreciated! Thanks!

Pivot the model to a high Y coordinate and let it fall…?

For all of these you need every part of the model to be unanchored, and every part to be welded to the RootPart of the model, or PrimaryPart.

Sorry that i havent explained it, but i have a platform on a height, and model needs to fall from the platform, thanks for the answer btw! I`ll try apply impulse rn
