This question is specifically for ateacher who is training.answers should be based on teaching physics only.

So you know what you have to teach. Physics also develops on itself a lot, so having a structured order of topics makes learning easier for the students.

Go to your local physics professor. If you are correct, (s)he will no doubt help you to get it published. If you are incorrect, (s)he should be willing to show you where your math is off.

Write it up and send it to a physics journal. You'd get credit for your discovery if it is valid. If it isn't, they'll let you know.

Glad to see you're thinking, but this is an easily answered question.  \n\nTake for example a magnet.  Regardless of what is in front of your magnet it will still attract an object to a distance equal to its strength.\n\nex:\n\n.....(|)<<<< <[]<<<<<<<[]          \n\n......^..............^...... ......^\nMagnet......Metal..... ..Metal\n.................Object.... Object\n\nThe magnet is going to exert force on both of the objects without interference from first object.  \n\nBased on your definition of propagate...come to your own conclusion...that is the joy of thinking...we all have our own thoughts.

I am sorry I can not provide you with an answer to your question. However it might help you get more answers if you put this question in again but put it in the Science and Mathmatics section. Under Physics. I think there are more people willing to help you out there!

Since the piece of cheese is at rest. and no net force is acting. by Newton's First Law of Motion, it would continue in its initial 'state of motion'  which is rest here (since it was initially at rest) ....all other choices would violate the law!. got it dear!

Read Newton's 3rd law of motion.\nAlso, use F=ma to figure out your acceleration.

This is conceivable, but only in a very low/no gravity environment.  Thanks for your thoughtful question.

http://www.sciencebuddies.org/mentoring/project_ideas/home_Phys.shtml?gclid=CNDljtrK6IgCFQ7eSgodNw4Ssg\n\nthere are MANY projects available getting more complex as you come to the bottom of the page.

A level Physics Books are available on market which are quite good!\nAdvanced level Physics By NnELKON and Parker should give good insight!\nBEST OF LUCK the important thing is NEVER EVER GIVE UP!

Well i am taking physics class this semester and we have to use websit to do our home work so please go to\n\n\nwww.masteringphyiscs.com\n\nyou will find all the topic for physics 1, 2 and 3...\nif you need help to search for the any topics than contact me...

i doubt your teacher couldnt answer these unless (s)he is not actually a physics teacher\n\nc and a\n\nthe initial momentum is 4kgm/s\nthe final momentum is conserved so it is still 4 kgm/s\nmomentum is mass*velocity\nmass is 1+3= 4kg\nv = p/m = 4kgm/s / 4kg = 1 m/s\n\nentropy is randomness or disorder, when the rooms are different temps, its like the temps are "sorted". there is order to the temperature. when they combine, there is no more order, the temperatures are more random instead of being focused around 2 different temps so disorder, or entropy increases

the best thing i found whe i studied physics was to memorize the formulas.  make flash cards and study those.  once you have the formulas down..start plugging the numbers in.

I think the author of the article linked to in your referenced web page (it's the link below) explains it well. One of the many  fundamental constants, the Fine Structure Constant, may have changed very slightly -- or it may not have. The data acquired so far is not conclusive, especially as decided by the scientific establishment, which generally demands pretty overwhelming proof of such a radical idea. And as the author says, confirming evidence must be obtained not merely from more iterations of the same experiment, but from totally different kinds of experiment, and he adds that precision in these other experiment types is not yet high enough to be useful as a proof.

C'mon, kid.  Go and read your book and do your homework.  I can understand if you are having problems with one problem, but you are posting this so that others will do your learning for you.  This is simple Newtonian physics.  Three laws you have to work with.  Basic, basic concepts.  If you can't handle this, then might as well give up your dreams of becoming a rocket scientist where you have to deal with special relativities and zero-gravity physics.  \n\nNow get moving!
