Gravity is due to the mass of the Earth (the density of its core), not to the spinning of the planet.
In the centre of a planet a person would feel weightless because the pull of the surrounding mass of the planet would cancel out.
Just come back to see what other answers had been provided and I'd love to know why I get two thumbs-down for this!
lol
Check wikipedia's entries on gravity and on weightlessness...
Or is somebody just trolling?

Spining? You mean spinning.
Gravity is caused by the mass of the earth.
The fact that the earth spins is another matter
Your question is grammatically wrong and also logically incorrect.
Even if gravity was caused by the earth spinning, it does spin anyway, so we wouldn't fly off.

Gravity is NOT caused by the spinning. Look at it this way: if you stand on the south pole, then the earth is spinning under and around you, but you are just going around once in 24 hours. Do you believe gravity will be zero for you?
Gravity is caused by the mass.
The spinning reduces the perceived gravity if you get progressively closer to the equator, but the strength is about 1/300 that of gravity at maximum, way too small to notice.

Gravity is caused because the earth is made of matter, that is to say it is a physical thing not just a radiation or some ethereal ghost.
The earth's gravity is not caused by it spinning. It spins because of gravity.
We do not fly off the earth because we are made of matter and gravity attracts matter to matter and the earth has a lot of matter so we stick to the surface.

1) Gravity is not caused by the Earth spinning. It is caused by the mass of the Earth.
2) Gravity keeps us on the Earth.

Gravity is not caused by the Earth's sspin. Gravity is an attractive force hat is a fundamental attribute of any material object (mass). Its a very weak force--far too weak for us to be able to detect the slight attraction caused by small objects--but the Earth is so large that its gravity is powerful.
The Earth's spin is responsible for our day/night cycle--if it didn't spin, one side of the Earth would always face the sun and the othr would always be dark. But that spin WOULD throw us off the Earth if it wern't for gravity--its the force of gravity that holds us to the surface of the earth--and keeps our atmosphere from dissipating off into space.

Gravity is caused by the Sun not the Earth if the Sun was to vanish everything in the Solar System would float away. It is the Sun that keeps the Solar System going, the Earth has gravity because of the Sun's gravity.
I hope that this answers your question?

Gravity is caused by the mass of the earth not the spin.

The mass of the Earth causes the space around it to curve and compress. The force of curved space pushes any objects within the vicinity of the Earth's mass towards the Earth itself. This is gravity.

Gravity is *not* caused by the earth spinning!
The force of gravity is a consequence of the mass of the earth and the mass of the objects with which it interacts.
