Suppose for some reason the laws of physics change instantaneously, and gravity stops working. Like a light switching off.
I'm sure that would be the end of everything, but how long would it take, and how would it happen?
We know humans can survive 0 gravity for a while, so that's a matter of keeping air, water and heat around as long as possible. But eventually all the air, the water, the whole Earth will disintegrate out into space in a million directions. How long could someone survive, and how would they do it?
We're getting ejected from the solar system from minute 8 as the Sun's gravity gets switched off, so will very quickly enter a permanent ice age and die of hunger in weeks to months.
But even that is optimistic, with no gravity holding the Earth together, the escape velocity will be zero. Simply the act of running will send you into space.
The Earth itself will disintegrate. Whatever forces are keeping the planet from collapsing in on itself now are now free to push out, sort of like a mini, planetary supernova but without the bang.

Instantaneously. The Earth itself would lose orbit and go careening off into space at 67,000 MPH, loosing everything that isn't affixed to it in the process. You are trying to predict what would happen on Earth instead of "too" Earth and there would be nothing left to worry about.
the question is how long could people delay their doom.
theoretically the Earth's momentum would keep it near the sun for a while. Its velocity is 3.14 AU per year, and it wouldn't be moving directly away from the sun at that speed. So even after a year it would be closer to the sun than Jupiter.
If this happened when Earth's orbit was parallel to the sun's motion through space, it would just cruise along at the exact same distance, through inertia.
Other important factors, how long would it take the atmosphere to dissipate, could part of it be preserved; would there be problems with huge volcanoes as the Earth's crust weakens; what about the oceans
This needs scientists and engineers to study what to do about it.
making false reports to law enforcement is a criminal offense
yeah nice try Dr. Drakken.
but if you really need help on your homework, then I would guess pretty fast. Those air molecules would zoom off without gravity, and 3 minutes without oxygen is all it takes.

You are going that same speed in exactly the same direction as the part of Earth nearest you. You're not going to drift apart that fast.
Rotation of Earth is the bigger problem. You will drift apart pretty fast (but not that fast) from China, England, India. And that's why I'm worried about the magma and the molten core, but then again, that's a potential source of heat for a while.
I don't claim to know all the answers, only to show that the science is complex
Is there advance warning so people can "strap in" and not float away when it hits? Also, our atmosphere would accelerate away from the earth - breathing gets tough pretty quickly.

WOW, You are stupid.
Let's use a Hammer thrower. The Thrower is the sun and the ball at the end is the Earth The thrower spins and spins and all is fine with world, but suddenly they let go. What happens? It becomes a projectile away from the thrower. Everything continues moving in the direction it was at the instant of release. The Earth becomes a projectile away from the sun.
The Earth is also rotating, so anything on Earth would get the same treatment. Instant ejection. Your not going to drift apart that fast? Ummm, yes you are. Dip a tennis ball in water and then throw it up and spin it. What happens to the water? It's ejected in all directions, right? Atmosphere, oceans, people, cars, bugs, birds, airplanes, buildings, etc, all get ejected.

LOL.
This is the stupidest thing I've ever seen.
Yes, it’s stupid. Irrespective of where the earth is in its orbit, it will fly off from the sun such that its distance from the sun increases at the same rate subsequently. The sun’s motion through space doesn’t matter because the both the sun and earth share that same inertial frame moving through space.
