I’m going to say that initially we’d just become weightless and continue in a straight line, rather than in orbit around the Sun, just like the Earth beneath us.

But things would rapidly change. All the rocks beneath us are compressed by the material above them. If that force disappeared they would expand outwards with very high accelleration.

I will leave it to mv to tell us exactly how that would work out over 7 seconds :)

Well outside my expertise.

Maybe more dv’s area?

Or maybe it needs experts from several areas + suitable software.

You should be able to emulate it in something like Inventor and set gravity suddenly to zero.
