Why do people float in space[craft]?

Answer 1

Gravity doesn't exist in the space crafts.

Answer 2

no gravity

Answer 3

There isn't enough gravity in the space craft to pull them to Earth

Answer 4

Lack of gravity strong enough to hold them.

Answer 5

Lack of gravity.

Answer 6

I guess we are talking about a spacecraft in earth orbit.

It is a common misconception to think that a spacecraft in earth orbit, and its contents, are in "zero gravity".  It is in fact the earth's gravity that keeps it in orbit.  The reason why people are weightless in a spacecraft is because they are falling at the same rate as the spacecraft itself, so there is no relative motion between them and the spacecraft.  Anything in orbit around the earth (including the moon) is continually falling towards the centre of the earth - but the object in orbit is moving at just the right speed so, as it falls, the earth curves away so the object is still travelling parallel to the earth's surface.  This is true not only of the spacecraft but also of everything inside it, which is why objects in a spacecraft appear to float in mid-air.

Answer 7

There is no center of gravity. The earth rotates which in itself stops it from flying into the sun (the sun pulls it) That center is what keeps us on the ground. In space, there is none, it is just space.
