Assume mearth 5 98 1024 kg.
What is the speed of a satellite orbiting at that height.
Earth s own rotation at surface for comparison not an orbit 6 378 km.
Speed orbital period specific orbital energy.
Find its period of revolution if r 6400 km.
M earth 5 98 x 10 24 kg r earth 6 37 x 10 6 m.
What is the speed of a satellite orbiting at that height.
7 9 km s 28 440 km h or 17 672 mph 1 h 24 min 18 sec 31 2 mj kg low earth orbit.
As satellites get closer to earth the pull of gravity gets stronger and the satellite moves more quickly.
The height of the orbit or distance between the satellite and earth s surface determines how quickly the satellite moves around the earth.
Determine the speed acceleration and orbital period of the satellite.
Due to atmospheric drag satellites do not usually orbit below 300 km 190 mi.
A satellite wishes to orbit the earth at a height of 100 km approximately 60 miles above the surface of the earth.
An earth orbiting satellite s motion is mostly controlled by earth s gravity.
At an altitude of 124 miles 200 kilometers the required orbital velocity is a little more than 17 000 mph about 27 400 kph.
Objects in leo encounter atmospheric drag from gases in the thermosphere approximately 80 500 km above the surface or exosphere approximately 500 km or 311 mi and up depending on orbit height.
This converts to about 16 800 miles per hour.
Assume rearth 6 37 106 m.
All you have to do is put in the numbers.
The nearer to earth the faster the required orbital velocity.
Orbiting at earth s surface equator theoretical 6 378 km.
Solution for at what height above the earth is the acceleration due to gravity 25 0 of its value at the surface.
Human made satellites typically orbit at heights of 400 miles from the surface of the earth about 640 kilometers or 6 4 10 5 meters.
What s the speed of such a satellite.
465 1 m s 1 674 km h or 1 040 mph 23 h 56 min 62 6 mj kg.
What is the speed of a satellite orbiting at.
To maintain an orbit that is 22 223 miles 35 786 kilometers above earth the satellite must orbit at a speed of about 7 000 mph 11 300 kph.
