A spinning object does not create gravity. But it does create centripetal forces (also previously known as centrifugal forces) whereby an object traveling the path of a spinning object is propelled toward the outside wall of the spinning object, due to the force angled to the rotation of the circle counteracting the force of the smaller object traveling tangent to its path. The strength of this force is often measured in "G's". A "G" is equivalent to the force of gravity, ie: 2 "G" is equivalent to twice the force of gravity.
Inertia and angular momentum
No. Spin has nothing to do with gravity.
Yes, it does.
Yes, but we would die first because gravity holds down air (oxygen and nitrogen and other stuff) and if the gravity leaves, then there's no air to breathe. No need to worry. Gravity isn't going anywhere any time soon.
Gravity isn't necessary for human life, as we can see on the International Space Station, where crew members spend months with no gravity at all. But even if gravity were absolutely essential, that would not be a problem on Mars, which has plenty of it.
Weight divided by volume is density. Usually it is expressed as mass divided by volume. That is why a unit for density will be something like grams/liter, because mass is on the top and volume on the bottom.
The depends. If they're researching the affects of zero gravity on biological tissues, then yes. If not, then they just need to know the effects that being in space will have on their own body, such as loss of bone mass.
no
you don't need air in space because there is no air in space at all! but in space they do have really small gravity!
Because theres no gravity.
No, kites need both wind and gravity to work.. and neither of those are in space.
There's no gravity in space - this affects their muscles. Exercising keep the muscles toned.
They need to wear something that is thick and something that is a space suit... they for sure need to put their pee on their face.
need gravity and you wash off with a wet washcloth
For the design of the probe an understanding of gravity is not required. However, to get the probe into space and into a stable orbit round a chosen body an understanding of gravity is required. Thus it is the launch vehicle design where an understanding of gravity is needed.
Because there's no gravity & you need gravity for you to push against the ground resulting in exersice
Without it you would be floating in space or wearing heavy shoes to stay on the ground.
Yes, but we would die first because gravity holds down air (oxygen and nitrogen and other stuff) and if the gravity leaves, then there's no air to breathe. No need to worry. Gravity isn't going anywhere any time soon.
no nope, because every chores need gravity. in outer space there's no gravity, so it's not easy.
Without gravity we could not stay on the surface of the Earth -- but that wouldn't matter, because gravity is what keeps the Earth from flying apart.
