Hi everybody, I'm following a course of physics and I'm going to do a
little report about the moon landing. I have to insert the following
points inside:

-description of the physical phenomenon
-description of the experimental machinery and procedures
-data
-data analysis
-discussion

The first 2 and the last point aren't a problem.
Instead it's kind of hard to find all the information I need for the 3rd

and 4th points.

I need to find all the most important data of the Apollo mission:
weight, thrust, acceleration, etc.. practically all the information
needed to transform the Apollo landing in a problem of physics.

I chose, as the most representative of a moon landing, Apollo 11.

The course of physics I'm following is about basic physics (newton's
laws, universal gravitation's law,  etc.)

Since now I took all these information
 http://www.flatoday.com/space/explore/manspace/apollo/apollo11.pdf
 http://www.thebest.net/jduncan/pdf/a11techsum.pdf

In the data analysis section I was thinking about starting from
the third law of motion to arrive to the rocket equation, it is well
explained in this page
http://www.jps.net/ethelen/rocket-eq.html
In this part I will explain the principle which constitutes the basis of

rocket science, therefore I'll explain why a multi stage rocket is the
cheapest solution.

Then I wanted to insert the universal gravitation's law and go from it
to the concept (and equation) of escape velocity.

Then, the problem is, I don't know if it makes any sense analyzing the
"whole" data, since putting all the data I can get about the
acceleration, thrust, velocity... into those equation would require even

more data (i.e. changing gravity in time, Coriolis force).

I don't *have* to do such a complex thing, anyway, I do like this topic
and I want my report to be good.

So, another thing I'm asking you: what would you insert and what would
you omit in the data analysis?
As i said before, the data analysis part has to look like a quite long,
basic physics problem.

My report won't be "round trip".
It'll be basically divided into:
-Ascent phase
-Earth orbit phase
-Translunar phase
-Lunar orbit phase
-Descent (moon) phase

Thanks a lot, Ippolito Forni

PS
I'm sorry for those readers where this message is pretty OT, but I tried
to send it on sci.space.science and sci.space.tech many times and it
never got posted. Maybe the moderator doesn't like it for some reason.
