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.
What Keeps a Satellite In Space?
Once a satellite is launched into orbit, the force of gravity tends to pull it toward the Earth. But by moving fast enough, it falls in a curved path and circles the Earth. So orbit is something like a controlled fall. If a satellite does not move fast enough, it will eventually spiral closer to the Earth and burn up in the Earth's atmosphere. The same balance of gravity and speed keeps the moon and the International Space Station in orbit.

What does a satellite travel path look like around the earth i have seen them as a wavy looking line not straight why is this?
an ellipse. the sinewave path on flat maps is because most satellite orbits are inclined/tilted with respect to the earth's axis. so the satellite moves north/south as well as around the earth.
Did the USSR launch the first space satellite?
* Artificial Earth satellite Sputnik 1The first successful satellite launched by the Russians (The Soviet Union at the time) was Sputnik 1 on October 4, 1957. It was released during the Cold War and it caused a space race between the Americans and the Soviet Union. Apart from being the first satellite to be launched into space, it also helped us to better understand the upper atmosphere, including the radiation belts and the ionosphere. It traveled 18000 miles per hour so it only took about 92 minutes to travel around the Earth.* Russian satellite countriesCountries of Eastern Europe adopted Communist governments following World War II and were called "satellite" countries of the USSR, which was dominated by Russia. They were collectively known as the Warsaw Pact countries for the military treaty to which they were signatories. The first country was Poland, partly occupied by the USSR in a 1939 arrangement with Nazi Germany.
If an object left Earth which direction would it travel due to inertia and Earth's rotation?
It would depend on the objects location, time, and the gravitational pull on the object.
Do roller coasters have motors?
No, they travel with gravity after their travel up a lift hill or after a launch.
Why does a space shuttle have to travel so fast?
Space shuttles must travel at 11km/s so that they can escape the force of gravity. the force of gravity is approximately 9.81. If you don't travel at a greater speed than the force of gravity, the rocket will not launch.
How fast would the rocket launching that satellite have to travel relative to the launch site if you launched it from a point on the equator?
7.98m/s
What is the affect of weight on distance paper rockets travel?
it is the gravity affects the weight
Why does a satellite travel at a greater speed when it is closest to earth?
The gravity is greater the nearer to Earth you go. The same is true for all planets.
If gravity did not affect the path of a horizontally thrown ball what would happen to the ball?
travel horizontally
In an atom the electrons travel around the nucleus somewhat like a satellite orbits the earth The force that keeps the electrons in orbit is the?
Repelling Force of Gravity
If a satellite is travelling in orbit around the earth and the gravitational force drops to nil what will happen to the satellite?
Without gravity, the satellite will travel in the same direction it was going when gravity went to nil. This is due to the object's momentum, and the satellite will go off into space. And if the gravitation were nil to begin with, there would have been no orbit in the first place. The question is problematic, since planets will always have gravity. Picture a ball on a string that is being whirled around by someone. If the string snaps, the ball continues to move in the direction it was going at the moment the string snapped. It flies off in a tangent, and the satellite will do the same thing if gravity is suddenly reduced to zero.
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.
Do you fall faster when higher?
no gravity pulls you at a steady speed. however air presure and movement WILL affect your speed of travel.
How far can a nuclear bomb travel?
A gravity dropped nuclear bomb could fall several tens of thousands of feet from bomber to detonation. A ballistic missile's warhead could travel tens of thousands of miles from launch site to detonation.
Does Gama rays travel faster than visable light?
No, no wave, particle or form of information can travel faster than light. Even the effect of gravity is not instant. If our sun disappeared it would take the EXACT amount of time for us to see the sun extinguish as it would for the gravity to dissipate and have us launch out of orbit.
