Around any single central body, objects in smaller orbitstravel at higher speed than
objects in larger orbits.
Also, for a highly elliptical orbit, like that of a comet, the speed is greatest when the
object is closest to the central body, and slowest when the object is farthest out.
What else can I help you with?
What happens when light passes into a material where the speed of light is faster?
-- Its speed increases. -- Its wavelength increases. -- It refracts away from the normal to the interface at the point of incidence.
Do planets revolve around the sun at the same speed?
No, planets do not revolve around the sun at the same speed. Their orbital speeds depend on their distance from the sun - planets closer to the sun have shorter orbital periods and faster speeds, while those further away have longer orbital periods and slower speeds.
Orbital speed is the speed with which a planet moves around the Sun This speed is determined by?
The mass of the Sun and the distance between the planet and Sun. As the Sun's mass is (more or less) constant, all we need to know is the distance. Technically this is called the "semi major axis" of the elliptical orbit. (If you wanted to be really, really accurate the mass of the planet does have a very very small effect.)
How does comet Halley's orbital speed change as it orbits the sun?
It accelerates towards the star. This is due to the increased force of gravity which is inversely proportional to the square of distance between the masses; as they get closer, gravity pulls harder. An increased force means a greater acceleration due to gravity.
What is the speed of the moon around th earth?
The average orbital speed of the Moon around the Earth is approximately 1,022 kilometers per hour (about 634 miles per hour). This speed can vary slightly due to the Moon's elliptical orbit, with its speed increasing as it approaches Earth and decreasing as it moves farther away. The Moon completes an orbit around the Earth roughly every 27.3 days.
Explain why the relationship between orbital speed and distance is the same as that between gravity and distance?
gravity is that keeping the orbital speed from falling or breaking loose. and the distance away = time
What happens when light passes into a material where the speed of light is faster?
-- Its speed increases. -- Its wavelength increases. -- It refracts away from the normal to the interface at the point of incidence.
An earth satellite in a elliptical moves with what speed?
The speed is variable; faster while closer to the Earth, and slower further away. But the actual speed varies by the orbital distance.
Which planet has the greatest variation of orbital speed?
Mercury has the greatest variation of orbital speed among the planets in our solar system. This is because its orbit is highly elliptical, resulting in significant changes in its speed as it moves closer to or farther away from the Sun.
Which planet has the slower orbital speed Saturn or Jupiter?
Saturn is slower because it is farther from the sun. The farther away a planet is from the sun, the slower its orbital speed.
Which planets have an orbital speed of less than 18 km per second?
Jupiter, and planets further away from the Sun than Jupiter.
If altitude increases the required orbital speed of a satellite should?
For any body in a closed orbit around another body, the farther apart the two bodies are, the slower the satellite moves in its orbit.. When the Space Shuttle is in "low earth orbit", it moves faster than the Moon is moving in its orbit. A satellite in an elongated orbit, that spends some of the time close to the earth and some of the time farther away, moves fastest at its lowest altitude, and slowest when it is furthest away.
What is positive accelerations?
Positive Acceleration refers to the force acting on an object whose speed increases as it moves away from its original starting position. If the velocity is increasing along with time it is called positive acceleration, and if the velocity decreases it is negative acceleration.
Do all galaxies move at the same speed?
As with all space questions about speed, it all depends on your point of reference. Within the Milky Way, the orbital rate of the stars increase as you move away from the centre of the galaxy.
Do planets revolve around the sun at the same speed?
No, planets do not revolve around the sun at the same speed. Their orbital speeds depend on their distance from the sun - planets closer to the sun have shorter orbital periods and faster speeds, while those further away have longer orbital periods and slower speeds.
How does the time taken to complete an orbit change in a planet if the distance from the sun increases?
The time taken to complete an orbit increases as the distance from the sun increases. This relationship is described by Kepler's Third Law of Planetary Motion, which states that the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. This means that planets farther from the sun have longer orbital periods.
What happens if the speed around the sun decreases or increases?
If the speed around the sun decreases, the orbit will become more elongated and the planet will move farther away from the sun. If the speed increases, the orbit will become more circular and the planet will move closer to the sun. This change in speed can affect the length of the planet's year and the temperatures experienced.
