describe the application of physics in defence?

Of course, physical principles underly every weapon system or other artifact of war.  But even restricting ourselves to the deliberate application of known physical principles, we find that physics has been used for military defense for millenia.  Archmides supposedly used focusing lenses (though if it really happened it was probably done with mirrors, not lenses,) to set fire to the ships of invading enemies.  \n\nThe other way around works too.  Warfare has often inspired advancement in the knowledge of physics.  For example, Galileo's sketches of the flight of canonballs inspired his work on projectile motion.

Can't answer this one directly as memory fails me but try a book by A C Kermode called Principles of Aeronautics.  This is an oldish book but still in print and used in the Royal Air Force for all its engineers and technicians.

Inorder to relate brain mechanics to physics you would have to use the quantium electrodynamics or the theory of electrostatic "Like studying how the processor works" but instead of electrons you can use neurons (how various sections of the brain handle data or signals and what part of the body they affect if signal transmission is ineffective) \n\nRealy hope you find an answer I would realy want to know your progress good luck!

There is a very large book called "The Handbook of Chemestry and Physics"  This is a very good reference.\n\nAlso, at Barns & Noble there is a forumla sheet called Physics (SparkCharts).  Very helpful.\n\nFinally, look for the Physics for Dummies.  I have found that when tutoring and teaching, the explainations help me to better understand what is happening in terms that I can communicate.\n\nGood luck in your studies.

OK I'm cheating - I put this answer up a little while ago.\n\nA quick and dirty idea for a physics project would be one based on electromagnetism. Without knowing what grade you're targeting, a simple one that has a fair amount of pizzazz is to build a gauss rifle. Checkout http://sci-toys.com/scitoys/scitoys/magnets/gauss.html\n\nThe sci-toys site has some other pretty cool stuff that you might find useful as well.\n\nFor a more advanced example, you can make a small rail gun that applies similar principles but can have a much larger kick. Just do a search on "rail gun experiment".\n\nEnjoy!!

It is tough because it is so abstract. In Physics one, its all abou force, something you can relate to. In physics II it is more abstract forces like magnetisms and resistence of electricity.  You are not alone.\n\nI found versions of the following books useful to help relate things:\nPhysics For Dummies ® (For Dummies (Math & Science)) by Steve Holzner\n\nComplete Idiot's Guide To Physics (The Complete Idiot's Guide) by Johnnie T. Dennis\n\nPhysics for the Utterly Confused by Robert Oman and Daniel Oman\n\nThese three books take real world examples and show you ho to approach them and relate them in a number of ways. Sometimes it helps to have a source other than the professor and the textbook.

Basically you have the right idea. Use momentum (mass x velocity) for the motion and the sudden change in speed and/or direction (acceleration) and you get force x time = kinetic energy trying to rip you apart or squash you like a bug.

They use  Electricity and Magnetism ( by Purcell) \nBerkeley Physics Course. Vol. 2. (Edit.  McGraw-Hill) for Physics2 (elecricity and magnetism) \nand for statics must be: Statics (by Waclaw Zalewski and Edward Allen).\n\n...why don't you get into the webpage? , they give you courses for free and also you can check his solved exams, it's pretty cool.
