preface

This site is intended for online physics help in high school physics and college physics for any student who wants to get online quick detailed info about any physics law, formula and physical quantity used in physics, from Classical Mechanics to modern Quantum Physics, and who is going to use it regularly in his study.

If you are a student who wants to get physics homework help, or is going to solve physics problems, do physics assignment, homework, lab, or prepare for physics exam, this site will provide you invaluable help. If you are a high school physics tutor or college physics tutor, this site will provide effective assistance for your day-to-day work. If you are just interested in physics and want to understand or recall any physical quantity, physics formula or physics law, then this site will help you to do it online by the quickest way. Just open the corresponding section of physics online guide and get immediately the information you need.

This site contains main information about physics, most frequently used in practice. But physics is such an unlimited human endeavour that it undoubtedly cannot be represented completely on any web site. Therefore if you find information in any section of the guide as insufficient and want to get more detailed information, you can always ask the author of this site for additional information. I can provide you as well the efficient online help in applying formulas of this guide for solving any physics problems, assignments, or homework, in accordance with terms of my online help service.

Using of this site is free of charge for anyone and doesn't impose any restrictions on you if you don't use this site for commercial purposes without permission of the author, and don't violate the terms of use. Nevertheless I'll gladly accept any financial support for this site from anyone who found this site to be useful, and wants to use it regularly in his practice. The funds can be sent to me using my payment details.

I wish you good luck in using this physics help site,

quick physics reference guide

The basis of this site is online physics reference book. This online physics tutorial contains brief detailed description of all physics laws, formulas and physical quantities, used in high school physics and college physics courses, in all its subjects: from Classical Mechanics to Quantum Physics. In addition to mathematics notations the detailed graphical illustrations to all physics laws with physical quantities are given, taking into account their vector nature. This will allow you to understand the physics laws much more effectively.

In order to get help just open the physics guide, and choose the corresponding section of the catalog tree in the left part, which has usual form and includes the following subjects:
