staying ahead of the pack........

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.

20. In taking notes be sure to include explanations.

21. Have an orderly, well-organized procedure for working problems.

22. Do more problems for practice than the assignment calls for.

23. Review your problems by working them forward and backward and by doing variations.

24. Memorize, for convenience only, a few of the most important fundamental formulas and for the
