Does a human body have a gravitational force?

Answer 1

according to the general theory of relativity gravity is created by a curvature of space. Theoritcly any object with mass would curve space thus creating a gravitational field. However the mass of a human is not significant enough to create any significant curvature of space. Further to that any curvature created by a persons mass is outweighed by the curvature created by the earth's mass.

Yes. If humans had no gravity, we would be weightless, and this would make life on earth exceedingly difficult. The argument that earth has gravity doesn't address the issue. Gravity is a mutual attraction between two bodies that have mass. In order for humans to have no gravity, we would have to be completely without mass. Any object with mass has a measureable gravitational field.

Answer 2

Humans do need gravity because after extended periods of weightlessness it has been shown that the calcium content of bones decreases. Without the stress of opposing gravity, bones would thin out and become much more easily breakable. After spending enough time in a weightless environment without adequate exercise to substitute for the effect of gravity, a person's bones might become so fragile that he would be unable to survive the return to a gravity environment.

Answer 3

Yes. If Earth attracts you, say, with a force of 700 Newton, then it follows (from Newton's Third Law) that you also attract planet Earth.

The gravitational attraction between two people is insignificant for most practical purposes, but it does exist.

Answer 4

Yes. You can even measure it. Step on a bathroom scale, and the display on the scale

shows the magnitude of the gravitational force between you and the earth.

And when you jump gravity pulls you down.

Answer 6

yes, you could breathe without gravity because it has nothing to do with your breathing. but without gravity we could float all the way in space. and in space we can't breathe.

Answer 7

There is gravity in everything including the human body.
