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.

Answer:
Hii (name)
Hope this letter finds you in good health. Hope your studies are going well in Bangalore. All of us miss you terribly, especially Mom, so try to visit us soon.
Mom was telling me that you are eating a lot of junk food these days. You are a smart kid, you should know that it is not good for your health. Junk food slows you down, it can make you obese, it decreases your immunity and metabolism which eventually leads to health problems. I know sometimes you want to indulge in such foods, but don’t make them a part of your meals. They don’t provide you nutrition as much as your hostel food will. If you want money to buy healthy foods, we will send you some, but don’t burn our money in such things. Be a conscious person. Eat healthy and advise your friends the same.
Stay healthy and happy .
Yours lovingly,
(name)
