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.
The period of a satellite is defined as..?
the time it takes the satellite to travel around the earth once
What is one thing that seems to move across the sky but does not?
a satellite in constant orbit in syncronisation with Earth - a stationary satellite
How do satellites travel around the world?
Satellites are able to travel around the earth by virtue of a phenomenon called centripital force (centrifugal force is a misnomer to the opposite effect). Imagine, an object traveling in one direction will continue to travel in that direction at the same speed unless acted on by a force (Newton cleared this one up for us with some degree of confidence). So if a satellite is launched into space the earth's gravity is going to pull it back toward the earth, however since the satellite is already traveling at such great speeds in a path that has been determined so that the velocity of the satellite always manages to be perpendicular to the force of gravity on the satellite. In this way the satellite manages to travel in an ellipse around the earth without additional propulsion.
Is it true that an astronauts mass is less on the moon than on the earth?
dear,mass is constant through out the universe.it doesn't matter u travel from one galaxy to other it will remain constant unless u travel with significantly high speeds comparable to speed of light.thats what Einstein's theory says.
Where would a satellite revolving around earth land if it crashed?
It will most likely burn up through the earths atmosphere on re-entry. The satellites travel at very high speeds, and are not designed to withstand the brunt of the earths atmosphere at the speeds at which they orbit the earth. You might get some bits left over, but these should be quite small. Operators try to land the satellite in the sea once it has reached the end of its life.
How do you use 'orbit' in a short sentence?
As a noun: The rocket placed the satellite into a high Earth orbit. As a verb: The satellite had to travel very fast to orbit the Earth.
Why a sound wave can't travel from a satellite to earth?
A sound wave can not travel from a satellite to earth because there is not an atmosphere in space. The sound wave has no way off traveling through the air because there isn't any air.
Why does a satellite travel over different parts of the earth?
Because most satellites are not 'geostationary'. A geostationary satellite orbits the Earth at the same speed that the Earth spins on its axis - such as the GPS grid, or TV relay satellites. Most satellites travel faster or slower than the Earth spins.
Draw a diagram showing the motion of a satellite around Earth is the satellite accelerating?
WikiAnswers cannot support diagrams - sorry. A satellite around the Earth will have an elliptical or (in some cases) a circular orbit. The satellite is constantly accelerating towards the Earth due to the gravity between the Earth and the satellite. However, because of the satellite's tangential velocity, it stays at a relatively constant distance from the Earth.
How does gravity affect the launch and travel of a satellite?
It has to get up to 7km a second to get out of earth's orbit, then it orbits around earth.
What is propogation delay in satellite?
A propagation delay is the amount of time it takes radio waves to travel from the surface of the Earth to the satellite and then back down to the Earth. The calculation of the delay is based upon the altitude and position of the satellite systems.
