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.
What else can I help you with?
Do astronauts need to know biology?
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.
What would happen if the force of gravity were to disappear suddenly?
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.
Is there need of gravity on mars for human life?
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.
Why do things need to be lightweight in space?
Objects sent into space need to be made as lightweight as possible due to the huge cost. A large amount of fuel is needed to achieve the required escape velocity and orbital speed for every kg sent - this could be as much 10,000 US dollars per kg (or 22,000 US dollars per pound)
Can a man lift one sack of rice in outer space?
Yes, a man can lift one sack of rice in outer space because there is no gravity to counteract the movement. However, he will need to be careful about controlling the sack's movement since it will float freely in the weightless environment.
Do you Need air in space?
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!
What do astronauts need to wear to go into space?
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.
Why doesn't your heart need to work as hard in space?
Because theres no gravity.
Would a kite work in space?
No, kites need both wind and gravity to work.. and neither of those are in space.
Why do astronauts need exercise in space?
There's no gravity in space - this affects their muscles. Exercising keep the muscles toned.
How would an astronaut aboard a space shuttle go about dropping an object down to earth?
The astronaut would release the object outside of the space shuttle and let it fall towards Earth due to gravity. The object would follow a trajectory back to Earth's surface without the need for further propulsion.
How do astronauts shower on the space shuttle?
need gravity and you wash off with a wet washcloth
Why do engineers designing satellite and space probes need to understand gravity?
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.
Why would exercise be difffrent in space than on earth?
Because there's no gravity & you need gravity for you to push against the ground resulting in exersice
To reach outer space rockets must escape what force?
To reach outer space, rockets must escape the force of gravity. Gravity is the force that pulls objects towards the center of a mass, such as the Earth. Rockets need to generate enough thrust to overcome Earth's gravity and reach escape velocity to enter outer space.
Why is gravity something that you need to have to live?
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.
Is it easy to do regular chores in spaceship?
no nope, because every chores need gravity. in outer space there's no gravity, so it's not easy.
