A satellite in an elliptical orbit gains speed when it?
A satellite in an elliptical orbit gains speed when it moves closer to the body it is orbiting due to the conservation of angular momentum. This increase in speed occurs as the gravitational force from the body pulls the satellite inwards, causing it to accelerate.
A satellite in an elliptical orbit travels at constant what?
If the path is perfectly circular, yes, the speed is constant. This should not be confused with the velocity, because while speed is constant, its direction is not; therefore velocity is always changing.
Gravity affects the speed of a satellite in an elliptical orbit?
Yes. Gravity affects EVERYTHING.
What is the speed of a satellite that moves in an eliptical orbit around the earth?
If a satellite is in an elliptical orbit around the Earth, the Earth will be at one of the focii. The speed of the satellite will then constantly be changing. It will move the fastest when it is nearest to the Earth (perigee) and slowest when it is furthest away (apogee).
Why does the speed of a satellite undergo change in an elliptical orbit?
The speed of a satellite changes in an elliptical orbit because the satellite moves faster when it is closer to the central body due to gravitational acceleration, and slower when it is farther away. This change in speed is necessary to balance the varying gravitational force experienced by the satellite at different points in its orbit.
At what part of an elliptical orbit does a satellite have the greatest speed the least speed?
in the orbit of a planet there is a point called perihelion which is closest point to the sun and aphelion which is furthest from the sun . Moment of a planet in it's elliptical orbit reaches it's maximum in perihelion
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
What can you infer about the linear velocity of a satellite in an elliptical orbit as it travels from perigee to apogee?
The linear velocity of a satellite in an elliptical orbit increases as it moves from perigee (closest point to Earth) to apogee (farthest point from Earth) because the gravitational pull is weaker at apogee, causing the satellite to speed up. At perigee, the satellite moves faster due to the stronger gravitational pull from Earth.
A satellite in a low earth orbit moving faster than a satellite in a geosynchronous orbit?
YES As height increases, speed of satellite decreases.
If the mass of a statellite is doubled while the radius of its orbit remains constant then the speed of the satellite is increased by how much?
The speed of the satellite will remain the same regardless of doubling the mass, as long as the radius of its orbit remains constant. The speed of the satellite in orbit is determined by the gravitational force between the satellite and the celestial body it is orbiting, not the mass of the satellite itself.
How does the mass of a satellite affect its orbit?
The mass of a satellite does not affect its orbit. The orbit of a satellite is determined by its speed and the gravitational pull of the object it is orbiting around, such as a planet. The mass of the satellite itself does not play a significant role in determining its orbit.
Why does the speed of a satellite undergo change in elliptical orbit?
Because that's the way gravity works. If you take Newton's simple formula for the mutual gravitational force between any two objects, and if you have enough calculus and geometry to be able to do it, you can massage it around and show that closed orbits must be ellipses, and that the orbital speed must be greatest when the separation is smallest.
