Succeed in Understanding Physics
Physics is a branch of Physical Science concerned with the study of the physical properties
of matter. The knowledge of Physics is important for the development of the products we use. It is also an interesting and
exciting subject of value in many walks of life.
There is a great need for people who understand scientific principles and know how to think logically. Your knowledge
and skills in these areas can help you excel in school, advance your career or improve your business.
The purpose of these free online lessons is to give you a start at improving your scientific knowledge of physics that
will help you become a champion in the field. If you have any questions, send
us an email.
Note: We now have many lessons in audio, so you can read along the spoken word.

School for Champions
Champion a worthy cause
There are many problems in this world that need people to help in solving them.
If you see an injustice or someone in need and feel strongly about the situation, you can champion it as
a cause and work to solve the problem.
Help out
Some can simply give donations to a charity, while others can get involved and participate in the solution.
When you champion a cause, you are making a difference. That is an important purpose of the
School for Champions.
Some causes that need champions include:
Haiti
earthquake: How to help - A list of agencies in the Washington Post
Chile
Earthquake - How to help and other volunteer opportunities
Doctors without Borders, providing
aid to people whose survival is threatened by disasters or violence
Action Against Hunger, providing
solutions to world hunger
CARE, a humanitarian organization fighting
global poverty
There are also many agencies in your city that are looking for help.
Suggestions
This is just the start of our list. If you know of some charities or causes that need help, let
us know about it.
