A bowling ball is 10m above the ground and the earths gravity suddenly has no effects on it. What would happen?

It wouldn't act like a balloon, because it can't get bigger.
I guess it wouldn't just float there, because gravity would be helping it maintain a relative inertia in relation to earth's surface, rotation and orbit. Wind movement would be a factor if you're outside.
In a closed space, like a room?
I'm guessing it would drift to a corner, if it could be affected by the moons or the suns gravity.

Dude, it's porn on the Image Boards! What the fuck are you discussing math for???
It would have inertia from traveling with the earth (relative to the sun).
It would continue to move in that direction, but the earth would quickly move away from it as the earth rotates around the sun.
so, depending on the position/rotation of the earth, it's gonna fly away. fast.

as the earth rotates around the sun
Does not.

you would have to expend energy to lift it 10m above the ground, and if the earth's gavity has no effect on it, then where has that energy gone?
in b4 i find out i dont know physics at all

If it's outside, the wind will effect it more.
If it's inside a room, it'll slowly move around the room. You said gravity, not inertial dampeners, stupid.

Now, if you shielded the earth's inertia from the bowling ball, gravity won't matter. It'll punch a hole through anything in it's way at the rate of 60 miles a second.

It would fly off into space as it would now be acting like a balloon with density 0. Much like if you submerge Styrofoam underwater then release it.

Pressure effects it how? it's shape changes it 0

Swing ball on string in circle, string break, where ball go?

ball is assumed to be motionless when gravity is nullified.

Assuming the ball is hovering completely still at the moment gravity lets go, then the earths rotation would cause us to perceive the ball moving in a westward direction (though in actuality it's remaining still relative to the solar system).
Eventually the ball would hit a building, or tree, or something. At first it may smash through these items, but each impact would accelerate the ball in a line moving the same direction, and nearly the same speed as the Earth's rotation. We would perceive the ball float off into space (slowly?) and drift in that same direction until affected by the gravity of another body.

It would continue on the path in which that particular side of Earth was moving. If this occurred during Sunrise, it would begin moving towards the sun, and vise versa during sunset. Also, there would be the movement based on Earth's rotation. Basically, it would begin 'floating' upwards due to the centrifugal forces no longer being counteracted by gravity, although it may cease to to the wind resistance, assuming that the air is still being affected by gravity. At the north pole, though, Earth's rotation wouldn't affect it, although Earth's orbit still may. You would see the ball moving off in a curved motion. This all is assuming it doesn't make contact with any objects that are still affected by gravity or which are anchored to Earth.

the centrifugal forces
try that again use things that exist. but i get your point
It's like if you were to hold onto the edge of a merry-go-round, and then let go. Think of your inertia; your resistance to change in velocity. Your body constantly wants to travel in the direction it is going, but seeing as you're spinning with the merry-go-round, this is changing, causing you to be pulled outward. A ball moving at the same rate as a planet would do this, and at the point of release from gravity, it would keep its inertia in the same way the person releasing himself from a merry-go-round would. So yes, centrifugal forces do exist. >>21
Exactly like he explained it. >>22
You're correct, I forgot about gas's tendency to fill voids. :O
from earthling perspective ball would appear to go up and west, eventually "setting" like the sun as the part of the earth you are standing on rotates away from the ball.
Buoyancy force would be very small, as change in pressure in air over an elevation change equal to the diameter of a bowling ball is very small. (google buoyancy force or Archimedes for maths)
It would also diminish as altitude of ball increases, and reach zero when it leaves the atmosphere. I vote for ignoring buoyancy force.

the earth would come apart from it's own spinning right?
