Why cant a satellite in orbit around earth cant fall into earth because?
because of the gravity in our solar system. The sun keeps us (the earth) in its gravity. And we keep the satellite in our gravity. And it works like stone in thread and if we rotate it then stone will be at the other end of thread and will keep surrounding you.
Is a satellite orbiting earth free from earths gravity why or why not?
No, that's why it's orbiting the earth instead of flying off into space. To it takes a force to change velocity. Changing direction changes velocity, so it requires a constant force to travel in a circle--think of the tension in a string while you twirl a rock attached to the end. A satellite if falling toward the earth constantly. As a thought experiment, consider dropping a rock to the ground. It falls straight down. If you throw it straight sideways, it travels for some horizontal distance before it hits the ground. A bullet travels further. Now, if you could shoot something fast enough, it would travel so far sideways before it reached the ground, that the ground itself would start curving away underneath it, because the earth is a sphere. If you go fast enough, then you can go so far, that the ground curves away under you at the same rate that you curve in your path as you fall towards the ground. This is basically what a satellite does--it falls around the earth.
How do man made satillites orbit earth?
Man-made satellites orbit Earth by achieving a balance between gravitational pull and their forward momentum. When a satellite is launched, it is accelerated to a high speed, allowing it to enter a trajectory where the curvature of its path matches the curvature of the Earth. This creates a stable orbit, where the satellite continuously falls towards Earth due to gravity but also moves forward fast enough to keep missing it. The altitude and speed determine the type of orbit, such as low Earth orbit (LEO) or geostationary orbit.
How is a satellite placed in orbit and why it retains its position in space?
This can vary depending on the function of the satellite. In general, the satellite is launched by unmanned rockets or from the space shuttle payload bay at the correct altitude. After the satellite is released from the launch vehicle, the speed of a satellite is adjusted so that the rate at which it is being pulled back toward the earth is the same as the rate at which the earth is turning underneath it. So it is continually falling but not hitting the earth. This is what is also happening to the space shuttle when in earth orbit and the ISS. Satellites in geostationary orbit - where they appear to remain over a single point on the earth - must have a circular orbit for this to occur. That is why they are placed over the equator. Any other orbit is elliptical in shape. The problem that arises is that the earth is not perfectly round, even at the equator, and so the orbit of geostationary satellites must be adjusted every two weeks to compensate for this. The engines are remotely fired for the correct amount of time. When the fuel runs out, this can no longer be done. Orbital mechanics is a complex and detailed concept to understand. See some of the Web Links to the left.
How far does the earth fall if someone falls 2 meters?
the earth doesnt fall.
What do you call a projectile that continually falls around Earth?
A projectile that continually falls around Earth is called a satellite. These objects are thrown into orbit around the planet and their speed is balanced by the force of gravity, allowing them to constantly fall towards Earth while also moving sideways fast enough to stay in orbit.
A satellite is projectile that falls ot of earth rather than into earth?
Satellites are in constant free-fall. This simply means they are constantly being accelerated by earth's gravity. However, an orbiting satellite's lateral motion is sufficient that the acceleration caused by the earth's gravity causes it to continually circle the earth, instead of crashing to the ground.
Why do the satellites not fall while revolving around the earth?
. The speed of the satellite is adjusted so that it falls to earth at the same rate that the curve of the earth falls away from the satellite. The satellite is perpetually falling, but it never hits the ground!
A projectile that falls around the earth is?
A projectile that falls around the Earth is in orbit. It is continuously falling towards the Earth due to gravity, but its forward velocity allows it to stay in a curved path around the planet without hitting the ground.
What keeps a satelite in its orbit around the earth?
The velocity of the satellite along with the earths gravitational pull work together to keep a satellite from either flying out into space or burning up in the atmosphere. They have to launch a satellite at a precise speed to make sure that the speed at which the satellite falls to earth matches the earth's curvature. The speed is 8000 meters a second.
What will happen when a satellite falls down?
When a satellite falls out of orbit, it will typically re-enter Earth's atmosphere and burn up due to the heat generated by friction with the air. If any parts of the satellite survive re-entry, they will likely land in the ocean or in unpopulated areas.
What is the acceleration on a projectile as it comes down?
The acceleration on a projectile as it comes down is approximately equal to the acceleration due to gravity, which is 9.81 m/s^2 on the surface of Earth. This acceleration acts in the downward direction and causes the projectile to increase in velocity as it falls towards the ground.
Why dont satellites in orbit fall to the ground like a ball in orbit?
They're given enough tangential velocity ('sideways' speed, parallel to the earth's surface) so that the curve of the earth falls away just as fast as the satellite falls.
Why do the satellite not fall while revolving around the earth?
They do fall. But they're traveling fast enough so that the surface of the Earth falls away from them as fast as they are falling. Same thing that keeps the Earth from falling into the sun.
How is acceleration described as the projectile rises and then falls back to the ground?
acceleration remains the same
How can one make a spoon dropped from a satellite revolving around the earth land on earth?
If you have a lot of time, and a huge amount of expendable cash, you can place a reasonably massive satellite in orbit under the spoon. Over time the satellite's gravity will pull the spoon's orbit lower and lower. Eventually the spoon's orbit will decay and it will drop toward earth. Just wait. It will end up on Earth eventually. The satellite is already in orbit and will eventually fall into the atmosphere. Anything that falls off the satellite is going to eventually go 'down' to Earth.
What happens if a satellite slows down so much that it falls out of its orbit?
If a satellite slows down significantly and falls out of its orbit, it will begin to descend toward Earth due to gravity. As it approaches the atmosphere, it will encounter increasing friction, which can cause it to heat up and potentially burn up upon re-entry. If it survives this process, it may crash to the Earth's surface, possibly in an uninhabited area, or create debris if it breaks apart. In either case, the satellite would cease to function and be considered lost.
