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.
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.
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
Satellite orbiting earth at constant speed is accelerating?
Yes, a satellite orbiting Earth at a constant speed is indeed accelerating. This acceleration is due to the continuous change in direction of the satellite's velocity as it moves along its circular orbit. While the speed remains constant, the change in direction signifies that there is a net force acting on the satellite, specifically the gravitational force exerted by Earth, which keeps it in orbit. This type of acceleration, where the speed is constant but the direction changes, is known as centripetal acceleration.
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.
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.
Why can a satellite move around the earth in a circular orbit at a constant height?
A satellite can move around the Earth in a circular orbit at a constant height due to the balance between gravitational force and its centripetal force. The gravitational pull of the Earth provides the necessary force to keep the satellite in orbit, while the satellite's velocity ensures it moves forward, creating a continuous circular path. This balance allows the satellite to maintain a stable altitude without falling to Earth or drifting away into space.
How does the direction of motion of a satellite in circular orbit compare with the curve of earth's surface?
The direction of motion of a satellite in a circular orbit is perpendicular to the curved surface of the Earth. This means that the satellite moves parallel to the surface at a constant distance rather than following the curve of 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 Artificial satellite goes around the earth in perfect oribt with constant speed?
An artificial satellite orbits the Earth in a stable orbit due to the balance between gravitational force and its inertia. The gravitational pull of the Earth continuously pulls the satellite towards it, while the satellite's forward velocity keeps it moving in a curved path. This combination results in a circular or elliptical orbit, where the satellite's speed remains constant in the absence of atmospheric drag or other forces. Thus, it maintains a consistent distance from the Earth and a stable orbit.
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.
