If he is fortunate enough to find a region of space that is still Newtonian, and the acceleration of gravity
is constant at 1,000G for a long distance and a fur piece, then he falls
X = 1/2 A t2
= 1/2 (1,000G) (60)2
= 1/2 (9,800) (3600)
= 17,640 kilometers in one minute,
= about 10,961 miles.
Notice that if he starts from rest, the average speed of his pulverized bones and distended guts
during the minute is 294,000 meters/sec,
or "Zero to 659,000 mph in 60 seconds." THAT oughta set you back in your seat !

What suggests that Phobos and Deimos were captured by mars gravity?
The simple fact that they orbit Mars, suggests that they were captured by Mars' gravity.
Why isn't an astronaut in our solar system in zero gravity?
An astronaut can never be in zero gravity in our solar system, because there is gravity (usually) from the Earth, and always from the Sun. It is important to distinguish weightlessness from zero gravity. Weightlessness occurs in a gravity environment in which the person is freefalling, hopefully in orbit. In a freefall condition, there is no friction to retard your fall, so you feel nothing pressing against you, and thus you feel weightless..When in orbit around the Earth, an astronaut is in freefall, and is therefore weightless, but there is still gravity. When travelling between the Earth to the Moon, the astronaut is still in orbit around the Sun, and is therefore freefalling weightlessly.
How does the force of gravity on an astronaut orbiting in the space shuttle compare with the force of gravity on the same astronaut when she is standing on the earth s surface?
Gravity is proportional to the mass and inversely proportional to the square of the distance of the centre of the body or bodies.As the shuttle orbits at a comparatively low altitude and the mass remains constant the force diminishes only slightly. Being in free-fall does not mean there is no gravity.
When an astronaut in orbit is weightless is he-she still in the grip of earth's gravity?
Yes. That's why they're in orbit (and not flying off in a straight line). Note - weight is the result of resisting gravity, NOT being in a gravity field.

What anastronaut working in Space near the International space station says she feel weightless. What does she mean Does the astronaut no have weight?
It actually means that the astronaut is in free fall, and doesn't FEEL gravity. Gravity does affect the astronaut, so the astronaut will still be accelerated towards Earth. However, the astronaut won't feel the gravity.
How does Gravity affect astronouts in space?
Gravity from objects such as the Earth, the Moon, the Sun, or the Milky Way will attract and accelerate an astronaut. "Accelerate" implies that the astronaut's velocity will change over time.If the astronaut is in free fall (basically, the spaceship's engine is not pushing the spacecraft), then the astronaut won't FEEL such gravity.
what is it called when an orbiting astronaut and feels no gravity?
Weightlessness.
What suggests that Phobos and Deimos were captured by mars gravity?
The simple fact that they orbit Mars, suggests that they were captured by Mars' gravity.
Which is heavier a bowling ball or a astronaut?
a bowling ball is much heavier than a astronaut under the action of gravity
Is there gravity between the moon and an astronaut who is on the moon?
Yes. The moon's surface gravity is about 1/6 what it is on Earth.
Why astronaut's cannot stand straight on the moon?
Gravity. No Gravity causes them to drift around and have no control over were they are going.

Can gravity be captured?
A good question, however to control gravity you would have to control time
Are objects lighter when the gravity is weaker?
One example is how light an astronaut weighed when standing on the moon. As there is very little gravity on the moon, the astronaut was able to jump much higher than he could back on earth.

What preparation does a astronaut need?
they need to train in lots of zero gravity and engineering
