I have 6 objects that I want to behave as one with rigid body simulation

    $\begingroup$ why don't you just join them? (ctrl-j) if you don't wanna join, you can use rigid body connect -> fixed $\endgroup$

    $\begingroup$ Hello, INeed.. A general answer is often best prompted by a specific example. That would tell us, for example, why you might not want to join the objects, in your case. $\endgroup$

  • $\begingroup$ I have added a .blend file, I want the clock to fall while still having the animation for the handles $\endgroup$ Commented Nov 24, 2023 at 22:15

With clarification in comments: you have a clock; you want it to fall, while its animated hands fall with it but continue to rotate as they've been animated.

From your blend file, which has the hands already animated: parent each hand, Plane and Plane.001, to the clock body, Cylinder. Give Cylinder rigid body physics. Give the floor, Plane.002, rigid body physics, and set those physics to passive. Do not give any physics to the hands. Run the simulation.

After changing the starting orientation, and running a few frames:
