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.
Definition of a satellite?
i really honestly dont know the answer. so can you anybody answer it for me?
Why is shape of satellite footprint is irregular?
It is not irregular: it is simply the projection of a regular curve onto the surface of a sphere.
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!
Why a satellite doesn't hit earth as it orbits?
inertia makes it want to fly straight but gravity makes it curve
Why a sattellite is said to be in free fall?
Imagine firing a handgun while standing on earth with no one or thing around for the bullet to hit. The bullet will speed out of the gun, and as it moves it will trace out a curve as it gradually gets pulled to earth by the earth's gravity, and loses speed because of air resistance. It wil then fall to earth perhaps several hundred yards away. Now imagine climbing up a tall tower and doing the same thing with a high velocity rifle. The bullet will travel faster from the rifle than from the handgun but will still eventually fall to the ground under gravity and slow down because of air resistance, but in this case, the bullet might travel a mile or two before falling to the ground, and the curve its path of flight traces out will be much larger. Now imagine the satellite. When launched, the satellite travels fast like the bullet, but it will not slow down like the bullet because, as the satellite is launched into space, there is no air resistance as there is no air there. Similarly the speed at which the satellite is launched is sufficient for it to continue to fall to earth, just like the bullet, but in the satellite's case the curve it traces out is exactly the same as the curve of the earth. So, the satellite continues to freefall to earth, just like the bullets, but as the curve of the earth is exactly the same as the curve of the satellite's path, the satellite will never reach the earth. It's as if the earth was 'moving away' from the satellite as fast as it was falling towards it. This is what is meant by 'going into orbit' and it is why satellites and spacecraft have to escape the earth at great speed if they are to go into orbit. If they did not have the speed required (called the 'escape velocity') their curve of trajectory would be too small and they would fall back to earth before going into orbit.
How is quadratic equations used to make a satellite dish?
Satellite dishes are paraboloid in shape - that is, a parabola (a quadratic curve) rotated around its axis. The shape has the property that rays entering it are reflected to its focus of the paraboloid. If the receiver is placed at that point, the signal is picked up from the broadcasting satellite over a wide field of view.
What is satellite longitude in satellite communication?
satellite is satellite
Name the different kinds of satellite?

How the sine curve related to a curve?
Basically, it IS a curve.
What is the c curve and d curve in MCB?
c curve & d curve mcb difference
What is Difference between simple curve and simple closed curve?
simple curve is a curve which doesnot cross itself,it neednot be closed....... but a simple closed curve is a curve which is simple and also closed. every simple closed curve is a simple curve but not vice versa.
