Maiia said:well since I assumed orbital radius was 2Eradius, then
(GMearth/r)^.5= v
I plugged in (6.67*10^-11(5.98*10^24)/6.37*10^6)6.5= 7913.048m/s

The velocity of a satellite in orbit depends on its altitude and the mass of the object it is orbiting. Generally, the closer a satellite is to the Earth, the faster it will travel. Satellites in low Earth orbit have an average velocity of about 17,500 miles per hour (28,000 kilometers per hour).
The velocity of a satellite can be calculated using the formula v = √(GM/r), where v is the velocity, G is the gravitational constant, M is the mass of the object being orbited, and r is the distance between the satellite and the object. This formula is known as Kepler's third law of planetary motion.
Yes, the velocity of a satellite can change due to factors such as atmospheric drag, gravitational pull from other objects, or propulsion from onboard engines. In order to maintain a stable orbit, the velocity of a satellite must be constantly adjusted.
As a satellite gets closer to the Earth, its velocity will increase due to the stronger gravitational pull. This is because the object being orbited has a greater influence on the satellite's motion at closer distances.
The velocity of a satellite is directly related to its orbit. A higher velocity will result in a larger orbit, while a lower velocity will result in a smaller orbit. This is why satellites in low Earth orbit have a higher velocity than those in geostationary orbit.
