How does weightlessness occur in a space shuttle that is orbiting earth?

Weightlessness is a measure of how much resistance there is between an object and the local gravity. If you are standing on the ground, then there is 100% resistance between you and the pull of gravity. Your weight is equal to the pull of gravity on your mass. When you jump off a tall object, you are falling. You feel weightless because there is no resistance between you and the pull of gravity.
When you are in a shuttle orbiting the Earth, both you and the Shuttle are falling in such a way that you never hit the ground. This is called an orbit. You feel weightless because you are falling. You just never hit the bottom like you would on Earth.

Do all space shuttle launches occur in Florida US?
No
When did the Columbia Shuttle accident occur?
The Columbia Shuttle accident occurred on February 1, 2003.
When the earth the moon and the sun are in line what can occur?
When the Earth, Sun and Moon are in line an eclipse can occur.
Is the ISS a geostationary orbit or a polar orbit?
Neither. A polar orbit means that the station orbits at an inclination of about 90 degrees North (or South). This can occur at any reasonable altitude (apogee or perigee), typically around 250 and 350 miles. A geostationary orbit MUST have an inclination of 0 degrees--above the equator; AND have an apogee/perigee between 22,000--23,000 miles. The ISS was built and intended to be visited by the Space Shuttle. The Space Shuttle was incapable of orbiting higher than 500 miles. So if the ISS were in a geosynchronous orbit, the Shuttle could never have reached it. One of the disadvantages of a polar orbit is that one loses the velocity benefit of Earth's Eastward rotation. It takes extra fuel to place the same payload at the same altitude in a polar orbit, versus a typical Eastward orbit. The ISS is in a Low-Earth orbit with an apogee/perigee of about 250 miles, and an inclination of about 57 degrees.
How does the first quarter occur?
the rotation of earth
How does weightlessness occur?
When a force is present to oppose that of gravity. eg > Upthrust on a body in a liquid (body in a swimming pool) Centripetal force ( orbiting satellite or space station)
Does a sonic boom occur every time the shuttle enters earth?
Yes, the shuttle has a sonic boom whenever it reenters Earth's atmosphere.
Why doesn't a lunar or solar eclipse occur every 15 days?
The orbit of the moon is not perfectly uniform about the earth (the same can be said about the planets orbiting the sun). The alignment of the earth moon and sun has to be perfect for an eclipse to occur, it rarely is though.
Do other planets orbiting stars have seasons or eclipses?
Its most likely that they do. Any planet with an axial tilt will have seasons throughout its orbit. Eclipses of orbiting moons are also likely to occur on these exoplanets, though it would be rare to find an orbiting moon that is almost the same apparent size as the star - as with Earth.

No
What is the meaning of the expression 'window' in the context of a space shuttle landing?
'Window', when referring to a shuttle landing, refers to the period of time when a de-orbit burn can occur to enable the shuttle to land at one of the preferred landing sites (Kennedy Space Center is first, and Edwards Airforce Base if conditions are unsuitable at KSC). Usually there are only about three windows on a particular day on which the burn can occur. Should these be missed on each of the suitable orbits, the window for that day will be past, and more windows not available until the next day due to the earth's rotation and the shuttle's path around the earth.
Where does plasma occur on the earth?
where plasma occur on the earth
Why does nuclear fusion not occur on earth?
Because the conditions of temperature and pressure that occur in stars do not occur on earth
How does night and day occur?
Day and night occur because the earth rotates around its axis once every 24 hours. During each rotation the part of the earth facing the sun receives the light from the sun, and this is called day. The side facing away from the sun is cast in shadow and this is called night.
When did the Columbia Shuttle accident occur?
The Columbia Shuttle accident occurred on February 1, 2003.
How do most elements on earth occur?
Most elements on the Earth occur as oxides or silicates.
How many earth quakes occur a year?
About 50 earth quakes occur in each day so we can say that 18250 to 20000 earth quick occur a year.
