I'd like to have a group of debris fall from a ceiling onto the floor, but not have them drop all at the same time. Is there a way to set a keyframe that dictates when the object enters the simulation? For example, object 1 starts falling on frame 0, object 2 on frame 5, object 3 on frame 24, etc.

Yes, you can keyframe the Animated checkbox by hovering over it and pressing I:

When Animated is enabled, the rigid body will be controlled with the animation system. When it is disabled, the rigid body will be controlled by the rigid body simulator.

So can I set keyframes on this checkbox? Is that what you're suggesting? – Justin Apr 11 '14 at 3:45
@Justin Yes. When it is enabled, the object will not be controlled by the physics simulator. – gandalf3 Apr 11 '14 at 6:09
How do you apply this to a large number of objects at the same keyframe? – NᴏᴠɪᴄᴇIɴDɪsɢᴜɪsᴇ May 13 '15 at 3:32
@NoviceInDisguise If the objects don't have any other conflicting keyframes, then Ctrl L > Animation data can be used to copy keyframes. – gandalf3 May 13 '15 at 6:40
Im wondering what the use is than, if its animated it does not habe the physics. How can we have both worlds or is this not possible? – Rombout Versluijs Oct 28 '15 at 0:34
