Move a welded part on a moving platform

How can I move a part on a moving platform without it “drifting”?

I’m using Tween, and I set it to go to another part’s Position & Orientation (CFrame would move the whole thing and I just want that part). When the part goes to the position x, it stays behind, because obviously, the part is moving. How can I stop this from happening?

Can I see what you’re welding part is I’m not a pro in studio but one thing I know about welds is when you make a wheel it could drift away if you push it I don’t think anchoring in tweeting works? Could you anchor it

Use a body gyro or body velocity on the platform or weld it

Oh yes the default should be ok right I completely forgot about does thanks

Weld the part on the platform to the platform itself.

local weld = Instance.new("Weld")
weld.Part0 = Path_To_Part_On_Platform
weld.Part1 = Path_To_Platform

How so?

I have a bodyVelocity on the main part and the rest welded to it,

The main part, therefore every part, is moving at 3 studs per second (variable speed), so when the tweening is done it is 3 studs behind, constantly.
