Although the main purpose of education is to train people to think
clearly about problems in life, no doubt most students do not care
about finding the best methods for carrying on their chief
activity�studying.
It is obvious that musicians, athletes, or even good footballers develop
techniques appropriate to their activities. Obviously, there is a proper
way to study. The purpose of this article is to call to the attention of
beginning physics students methods for effectively studying physics.
A proper mental attitude toward the material to be studied is the
primary requirement. You must earnestly want to learn. Unless you
make up your mind to do a good job in your physics work, this write-up
will not help. Unfortunately, a made up mind alone will not help.
Learning physics takes work. This guide points out how you may work
effectively but it cannot tell you of short cuts because there are none.
Try out the various methods and then develop a system of study that is
suited to you.

them that really matters.
P HOW TO WORK PROBLEMS
because formulas without definitions mean nothing.
One of the very effective methods of studying
physics is to work problems. You may have in mind
merely a general idea of some point and hence
delude yourself into thinking you understand it.
Only when you can do a quantitative problem
without hesitation, however, and work directly to
that correct solution, is it certain that you understand
the subject. If your textbook does not have enough
problems, get another text or one of the many books
of physics calculations. If you solve problems ahead
of the class, you may have opportunity to ask
questions in class about parts you do not
understand.
In working problems, it is very important to do the
work in an orderly manner:
1. Read the problem carefully twice.
2. Reduce the problem to its essentials.
3. Picture ,draw and label a suitable
diagram.(very important)
4. List the given quantities and the required
quantities.
5. Put down some relevant principles (usually
in mathematical form).
6. Analyze the problem, think about it,
correlate the various factors, bring out some useful
ideas.
7. Check the problem.
8. Check the units.
9. Look critically at the answer. Does it seem
like a reasonable answer?
10. Look up the answer in the answer book.
11. If your answer is correct, review the
problem; otherwise correct the problem and then
review it.
Perhaps not every step is needed in every problem,
but most of the steps are useful in the majority of
the problems you will have to work
Be sure you know what the symbols stand for,
DEVELOP YOUR USE OF
ENGLISHay special attention to definitions. Although
in common terms such as force, energy, Pwork, and power often are used
synonymously, all of them have distinct, different
meanings in physics. Learn these meanings.
All students should own and use a good dictionary.
Definitions are important not because they may be
asked for in an examination but because a clear and
concise understanding of the meaning of a defined
quantity is essential to an understanding of it. Do
not merely repeat the words in the book to yourself
but study to understand the subject so that you can
give the definition in your own words.
Don't expect too much. A thing may have a
terrifying name (such as a prolate spheroid) but may
actually represent something simple (a football).
The sentence following a difficult one may clear up
the trouble.

f you have done your work carefully from day to day, reviewing for exams can actually be a pleasant
experience. In any case, begin your systematic review for the final exam two weeks before exam Iweek. Plan your work so that the day before the exam you will need to do no more than review the
previously learned and understood material. In that case some hours of work the day before the exam will
be all that is necessary.
During your study, try to anticipate exam questions and plan what your answers should be. If you have a
sufficiently good grasp of the material to be able to make up possible questions and then solve them
without your notes, you are practically assured of an A. This is a very effective kind of study, for in order to
devise good questions you must have studied the fundamental ideas.
MATHEMATICS IN PHYSICS
any students imagine that they are having trouble with physics when actually the difficulty
may be with their mathematical background which perhaps is too rusty to be useful. You Mshould be able to multiply 8,642 × 9,753 and get 84,285,426; without making a mistake; and
you should be able to do it within two minutes.
You are not good at arithmetic unless you can do it in one minute. (Some modern electronic calculators can
do it in less than a thousandth of a second).Since you cant do physics without maths, you must spend more
time to improve your mathematics.
