Henry and Ben got the basics of this, somewhat amusingly the fundamental
physics should be easy to test on the ground. Just drop your object. It
will switch from 1g towards earth to free fall with negligible drag due to
the zero velocity at the drop. Just like a rocket that was accelerating at
1 g then stopped. But like Henry said in flight there are a number of other
forces you will probably have to worry about.

All will move forward. Elastic deformation and external forces on the
projectile produce a differential between the two objects. You can see the
effects on some of the Space Shuttle and Soyuz flight videos.

Just checking assumptions, please advise.
Am I right assuming a mercury droplet or loose ball-bearing will not move
forward inside a rocket in vacuum the instant the motor stops? It then only
might start floating.
Nor will such droplet move forward inside a cannon projectile after it
leaves the muzzle since on that instant push force has stopped. As to
during the short residence time inside barrel, it might fly forward I
reckon.
