So are you implying that we have maximum potential energy on earth compared to center of the gravity and thus the most negative mechanical energy and what the rocket does is to reduce this mechanical energy when it puts the satellite in the orbit?

Of course launcher is doing something a little different with your comment. In the energy analysis only considered the beginning and end of the process. Actually launcher increases kinetic energy of the satellite and has no relation to the potential energy. Potential energy varies depending on the distance from the Earth. While launcher increases kinetic energy the potential energy decreases and in general, the mechanical energy is reduced. Duty of launcher is speed up satellite into orbital velocity.

In analyzing these issues always consider the energy difference.

The correct answer is up there if you want to learn something. Gravitational potential energy is negative, is maximum on the surface and does decrease the higher you go.

I appreciate your good intentions trying to answer my question. Not knowing something is not a bad thing. However you lack the ability to recognize when you don't know something. We Iranians call this compound ignorance. I have also noticed your tendency to attribute your own defects to others. For example you call others fools while you are the only fool there. This is called physiological projection. There is link below for you to know more about it. You may also want to visit a psychologist and you may as well thank me if and when you are cured.

Psychological projection - Wikipedia, the free encyclopedia

It's really funny to see how confident you are about your stupidity.
Anyway, never mind, I should not even start wasting my time in explaining these simple physics subjects to dumb people. Go back and start reading from "dovvom rahnamaayi" books, then you may understand what I have said.

intresting , usually when a Sat is falling the rate of decline increase but here it is very slowly decreasing

So you believe its up in space? I thought you said it was impossible to carry it up there?

She is so incredulous that she follows it day and night. You should have seen her about the Qaher, she just disappeared for 4 months, maybe to get some help in a psychiatry hospital.

I dont know where from u got it. I predicted it will last on orbit for about 2 months (instead of 1.5 year claims):

I think we owe Fajr's being the 2nd most tracked satellite to @500 and rest of his countrymen!

You're acting cocky over a 50 kg radio?

Cocky? Are you sure this is the word you wanted to use? There is nothing cocky about what I said. I just joked about his obsession.

Tracking Fajr is much more fun that stable satellites whose orbit does not change over years.

No in a post above you were worried if that Iranian rocket would ever carry that much payload in space
