I do not know how to thank you, you have taught me much that my teachers could not teach me. I have that project and have chosen to investigate Compton scattering / Compton effect. Then I read about it, I saw that the momentum is the key element. so I've probably other issues that I need to ask. but it will be later, please respond during the Christmas holidays?No, I think I've covered everything, but if you still have any questions, just ask.
Try a google book search …Can there is more fuller on Compton scattered? Then other links
you say that each okjekt has one quantity, then is my question: What comes this from the start? if we say a car, in order to it will drive so needs it no quantity from another item without it needs fuel in order to begin to drive. therefore, that one energy needs in order to can to drive with the car. if we take another example and it is then one runs. before I began to run had I no momentum, without in order to I will can opening so needs I to allocate a certain energy. this energy comes from the food that I eat. about now I run and since collides with another item that is placid comes a part of my momentum to be transfered to the item, but was come my momentum from? it cannot well come how as entire pcs, without it must come from something. I do not know about my English is understandMomentum is a quantity which an object has when it moves.
It can transfer that quantity to another object.
That quantity is never lost, it only moves from one object to another.
It measures the ability to move another object …
the more momentum you have, the more you can move something else …
the less you have, the less you can move something else …
if you do move something else, you must give up some of your own momentum.
hag is not good on English and I translate the text in google translates. but it is value loose
your google translator is really bad!have you a good homepages where it stand about business amount? would you kuna send little lhemsidor (web) to me thanks
have you easier level, I mean that my level is not so here advancedTry this free online book … http://books.google.com/books?id=bYP72LvvVwkC&printsec=frontcover&dq=momentum&lr=&client=safari&cd=31" by David P. Kessler, Robert Albert Greenkorn
Also The forces of nature by P. C. W. Davies.
(btw, your English is much better than the google translator … i recommend that you do your own translation! )
“When two bodies in motion impinge, if their centers of inertia move in the same straight line perpendicular to a plane tangent to the bodies at their point of contact , the impact is said to be direct and central.”
I can not really understand:
“the same straight line perpendicular to a plane tangent to the bodies at their point of contact”
I can not really understand:
“if the straight line described by the center of inertia of one of the bodies is not perpendicular to the tangent plane , the impact is said to be oblique.”

The "tangent plane" is the plane of contact between the two spheres …
imagine that, when they are touching, you put a flat piece of paper between them …
it will be tangent to both spheres at the point of contact.
http://www.pluggakuten.se/wiki/images/0/0e/Snett.jpg [Broken]Now, it's possible for one (or both) of the spheres to come towards that paper at an angle (though still hitting the same contact point) …
in that case, the centre of inertia is not moving perpendicular to the tangent plane.
