What is a sentence for weightlessness?
The weightless astronaut landed on Mars, which has no gravity.
If an astronaut is weightless orbiting the earth at 100 miles up would you experience weightlessness at the top of a 100 mile step ladder What equations would prove or disprove?
The person on the ladder would not feel weightless because they are not in orbit, they are simply at a high altitude. If they let go, they would fall straight down towards the earth's center just as any other object which is being pulled on by gravity.Orbit is achieved through velocity. With enough thrust, a rocket is able to propel an astronaut to a speed which will send him beyond the earth's gravitational field and straight into space (ie: "escape velocity"). However, by controlling the level of thrust and angle of inclination, the astronaut can be placed in an area of space that is somewhere "in-between" the pull of earth's gravity and the escape velocity. This is called "orbital velocity". The astronaut achieves ORBIT, and he is in a constant free-fall circling around the earth: not quite fast enough to escape the earth's gravity, but not so slow that he falls back to earth.When a spacecraft needs to return to earth, thrusters are fired in the direction of orbit, which decreases forward speed, and allows the craft to return to earth via the earth's gravitational field with help from atmospheric drag.
How does sunlight reach an astronaut on the international space station?
It arrives directly from the sun or comes in via the reflection off the earth, the moon, or anything else orbiting nearby.
What is so special about being an astronaut?
Being one of the few people who get to go into space, to experience living in a weightlessness environment, to look down on the earth from above, and to fully appreciate the vast emptiness of space. I guess what one person sees as being special will vary with the next, however there are many people that have an appreciation and a curiosity to wonder what it would be like.
Why do astronauts orbiting the earth experience weightlessness even though they are still within the earth's gravitational field?
When something is orbiting the Earth, it is actually falling toward the Earth. But because a space shuttle has such a great velocity (speed w/ direction) it misses hitting the Earth's surface. Image you throw a baseball. The baseball follows the path of a curve called a parabola, but the parabola is actually part of an eclipse (elongated circle). Now image if you threw the baseball so hard that when it fell toward the Earth, it actually missed the "edge" of the Earth following the path of the eclipse around the Earth. That baseball would then be launched into orbit. (Of course you would have to throw this baseball at a speed of 11 km/s).

How do you experience weightlessness on earth?
You can approximate weightlessness in a swimming pool. NASA astronauts practice maneuvers under water.
An astronaut inside a small space ship orbiting around the earth cannot detect gravity.If the space station orbiting around the earth has a large size can he hope to detect gravity?
If the size of the space station is large enough, then the astronaut will detect the change in Earth's gravity (g).
Is an orbiting astronaut subject to zero gravitational force?
The fact that he is orbiting means he is being held by the gravitational force of the Earth. If not for that, he would be headed out of the solar system.
How far from earth do you have to be to experience weightlessness?
You have to be outside of the gravitational pull in the atmoshpere. Answer: Weightlessness can be achieved:* in Earth's atmosphere in an aeroplane doing a dive or on carnival rides (Drop of Death)* when in orbit around the Earth or other body.* there are several points (Lagrange points)in the Earth/moon system where the gravitational attraction of the two bodies cancels out producing weightlessness.
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.
If the space station were in a geosynchronous orbit above the earth would the people be weightless?
The astronauts would experience weightlessness.
Why are astronauts in space weightless?
Although the Earth's gravity has a lesser effect on an astronaut orbiting the Earth in a spaceship than on a person on the surface of the Earth, this is not the reason why an astronaut experiences weightlessness. The space shuttle, International Space Station and most other manned vehicles don't get that far from the Earth. The Earth's gravitational attraction at those altitudes is only about 11% less than it is at the Earth's surface. If you had a ladder that could reach as high as the shuttle's orbit, your weight would be 11% less at the top. Put another way, a person who weighs 100 pounds on the Earth's surface would weigh about 89 pounds at the top of the ladder.
Space words that start with the letter w?
Weightlessness occurs in space. Astronauts circling the earth in space experience the feeling of weightlessness.
What area marks the boundary where the earth's atmosphere is constrained by gravity?
There is no boundary where Earth's atmosphere is constrained by gravity. Many feel that astronauts orbiting above the Earth are weightless because they are far away from Earth's gravity , but weightlessness is actually caused by the free-falling of an object that is in orbit.
How can we make weightlessness on earth?
You can't
If there is gravitational pull from the earth in the mesosphere all the way up to the exosphere why do object in that field experience weightlessness?
That happens because the objects are in free fall.
