How does radius affect orbital velocity?
As seen in the equation v = SQRT(G * Mcentral / R), the mass of the central body (earth) and the radius of the orbit affect orbital speed. The orbital radius is in turn dependent upon the height of the satellite above the earth.
What happens to the speed of an orbiting object if its orbital radius increases?
The greater the acceleration, the greater the change in velocity – this causes the object to move faster. This means that objects in small orbits travel faster than objects in large orbits. In order to change orbital speed, an object must change the radius of its orbit at the same time, to maintain a stable orbit.
What will happen to the orbital velocity if the orbital radius of a satellite is doubled?
The orbital velocity would double. Escape velocity is always orbital velocity, so we can multiply the answer for orbital velocity.
What happens to the speed of satellite if the height of satellite orbit is increased?
If the height of the orbit of a satellite increases, its velocity must also increase. Hence, if the height of the satellite from the surface of the earth increases, its velocity decreases.
What would happen to the orbit of a satellite if it’s distance from the Earth doubled?
Doubling the distance between an object and the earth’s center will decrease the acceleration of gravity by a factor of four. The acceleration of an orbiting satellite is equal to the acceleration of gravity at that particular location.
How does orbital velocity of a satellite vary with the mass of the satellite?
Assuming we are talking about the mass of the satellite (and not the mass of the body being orbited), mass does not affect the orbital speed.
What will happen if orbital radius increase four times orbital velocity?
I have a question says that “If the orbital radius of a satellite increase four times the orbital velocity will be …” and the answer is that the velocity will be doubled !!
What happens if the escape velocity is less than the orbital?
If escape velocity is less than orbital then the orbit will diminish which will result in the object crashing. If it is more then the object will be free in the orbit and will likely float into space.
How does an orbit break out of the Earth’s orbit?
The Apogee of your orbit which is the highest part of the orbit will increase in altitude too, and as you keep increasing the velocity, the apogee of your orbit will take place of the raising part P’ of your orbit. As you keep increasing the velocity, you will then reach the Escape Velocity of the Earth and will break out…
What does the angular momentum of a satellite depend on?
From the above equation, it is clear that the angular momentum of a satellite depends on both the mass of a satellite and mass of earth. It also depends upon the radius of the orbit of the satellite.
