What else can I help you with?
If a space vehicle is designed to orbit the earth very slowly should it be into a low or high orbit?
High orbit, Gravity weakens as you move away from its source, and although less centripetal force is needed to maintain larger circlular paths at a given speed gravity weakens at a greater rate.
What causes the moon to speed up or slow down slightly in its orbit?
The moon's orbit can be influenced by various factors, including gravity from other celestial bodies, such as the sun and Earth. The gravitational pull from these bodies can slightly speed up or slow down the moon's orbital speed. Additionally, the shape of the moon's orbit around Earth is not a perfect circle, which can cause variations in its speed as it moves closer or farther away from Earth during its orbit.
How does a planets distance from the sun affect its orbit speed?
Since the gravitational effect of the Sun decreases with distance from it, the planets farther from the Sun do not have to move as rapidly to remain in orbit. (In fact, the speed is what establishes the orbit, not the other way around.) So the outer planets, in addition to having much farther to travel in their orbits, are also moving more slowly. This combination means that outer planets take very much longer to orbit the Sun than do the inner planets such as Earth. By comparison, the length of time it takes (in Earth years) for each of the outer planets to make one complete revolution around the Sun: Jupiter - 11.9 Earth years Saturn - 29.5 Earth years Uranus - 84 Earth years Neptune - 165 Earth years
How fast do satellites traval?
Satellites typically travel at speeds around 28,000 kilometers per hour (17,500 miles per hour) in order to maintain orbit around the Earth. The exact speed can vary depending on the altitude and type of orbit the satellite is in.
An orbit in which a satellite travels at the same speed as the earths rotational speed is called?
That's a 'geosynchronous' orbit. If it also happens to be over the equator, so that the satellite appears to stay at the same point in the sky, then it's a 'geostationary' orbit.
What happens to earths oribit speed as it gets closer to the sun?
As Earth gets closer to the Sun during its elliptical orbit, its orbital speed increases due to the stronger gravitational pull from the Sun. This increased speed helps Earth compensate for the increased gravitational force and maintain its orbit around the Sun.
What will happen to the motion of a satellite if the satellite is put into an orbit where there is no sufficient velocity for rotation?
That would be "revolution", not "rotation". Let's assume you need a certain speed for a circular orbit. If the satellite (in this case) has a bit less speed, it will get closer and closer to the Earth, during half of its orbit. While doing this, its speed will increase; during the other half of its orbit, this speed will make it go away from the Earth again. The final result is that it moves around the Earth in an ellipse. This assumes, of course, that it doesn't approach the Earth too much. If it gets too close, it will be slowed down by the atmosphere, and eventually crash to Earth.
Where in our solar system are the planets which orbit fastest?
The closer planets are to the Sun the faster their orbit speed
If a comet is close to the sun how fast does it travel?
If any comet comes CLOSER to the Sun than Earth's distance from the Sun, its speed will be LARGER than that of Earth, which is 30 km/second.The exact speed will depend on how close the comet gets to Earth, and - to a lesser extent - on the exact shape of its orbit. If you know the orbital characteristics, you can get the speed using Kepler's laws. For a start, compare the orbit to Earth's orbit, using Kepler's Third Law.
When two artificial satellite revolve around the earth the one's closer and the one's further. which one revolve the earth with higher speed?
The one that is closer will move at a higher speed. The same happens, for example, with planets revolving around the Sun - the planets closer to the Sun move faster.
How long would be a second if the Earth would turn at a different speed?
a second will become less because it takes 365 days for the earth to orbit the sun and if the earth becomes faster it will take less day to orbit the sun, so if that happens time must go faster to keep up with the speed and time our earth takes to orbit the sun.
What is the maximum velocity that the Earth is able to revolve around the Sun without losing the ability to harbor life?
The speed of Earth is related to the position of its orbit around the Sun. At a higher speed, Earth would need to be closer to the Sun; at a lower speed, it would need to be farther from the Sun. In its current orbit, Earth moves around the Sun at a speed of about 30 km/second. Earth can't get much closer to the Sun (and therefore move faster) than that; for instance, Venus moves around the Sun at a mean speed of about 35 km/second, and it seems that Venus is too close to the Sun for life.
What happens to the shape of the orbit of a satellite orbiting the earth if the speed increases?
If the speed at every point of the new orbit is higher than the speed at every point of the old one, then the orbit is smaller, but it can have the same shape. ============================================ Another contributor added: going too fast may give the satellite an elliptical orbit, or may cause the satellite to escape the gravity of Earth if the velocity is too great
Why does the earth move so fast?
We have no real idea of what caused the Earth to form in the orbit that it did (rather than one a little closer to the Sun or a little further away) but the speed of the Earth in its current orbit is fixed by its distance from the Sun. A closer orbit would be faster; a more distant orbit would be slower. Nor do we know why the Earth spins at its current rate. These things happened billions of years ago. We may NEVER know what happened way back when to cause things to be the way they are.
What happens as the satellite get closer to the earth?
As a satellite gets closer to Earth, the force of gravity acting on it becomes stronger. This can result in an increase in speed and a change in the satellite's orbit. Ultimately, if the satellite gets too close, it may enter the Earth's atmosphere and burn up upon reentry.
What speed did sputnik orbit earth?
Sputnik 1 traveled at a speed of 18000 mph, completing one orbit of the Earth every 96.2 minutes.
If a space vehicle is designed to orbit the earth very slowly should it be into a low or high orbit?
High orbit, Gravity weakens as you move away from its source, and although less centripetal force is needed to maintain larger circlular paths at a given speed gravity weakens at a greater rate.
