From Keplers discovery, scientists were also able to infer that the closer a satellite is to an object, the stronger the force of attraction, hence it must travel faster in order to maintain orbit. Relying on this formula, we are able to see that the velocity required for orbit is equal to the square root of the distance from the object to the center of the Earth times the acceleration due to gravity at that distance. So if we wanted to put a satellite in a circular orbit at 500 km above the surface (what scientists would call a Low Earth Orbit LEO), it would need a speed of ((6.67 x 10-11 * 6.0 x 1024)/(6900000))1/2 or 7615.77 m/s. So really, a satellites ability to maintain its orbit comes down to a balance between two factors: its velocity (or the speed at which it would travel in a straight line), and the gravitational pull between the satellite and the planet it orbits. If youd like more info on satellites, check out these articles: Orbital Objects List of satellites in geostationary orbit Weve also recorded an episode of Astronomy Cast about the space shuttle.
I say it would be c to enjoy the simple feeling of flying
D is the correct option because it is the only one that is a fact.
A is opinion
B is a false statement
C is an opinion
Hope this helps!
