Then, read the problem carefully to determine what information is given, and what information you're solving for. From there, pick the formulas that have all of the variables except for the one you're solving for.

Past that, practice is key. If you do enough of them, you'll begin to see that the problems are all very similar to each other. You'll begin to recognize that you did "that problem" before with different numbers or going backwards.

Here are my suggestions:Originally posted by Gale17

1. There must be examples in your textbooks after each chapter. Read them and understand them thoroughly before attempting to do questions. As enigma has mentioned, the questions are quite similar to each other.

2. Practise makes perfect.

3. Find good reference books

4. Learn from mistakes

I remember 3 years ago, the time when I started to learn physics, I had a test on machanics after learning the relationship between displacement, velocity and acceleration. I started doing revision on the night before the test and felt really frustrated when I failed to answer the first few questions in my question book. I went back to read some examples first before attempting the questions again. Since the questions are quite similar, after reading the examples, I could tackle the questions well. I did more than 20 questions on this non-difficult topic.

Now my physics syllabus harder than that in 3 years ago. I remember once I did more than 100 questions on the topics rotational dynamics and simple harmonic motion fews day before test!

Work hard !

I suggest that you spend time (with a tutor if necessary) going through each equation and understanding:

What each term means and its signifigance.

Where the equation comes from. Not a detailed derivation, just enough understanding to know where each term comes from.

Any assumptions made in deriving the formula.

When the formula can be applied and when it cannot.

Once you have done this, practise questions from past exam papers or textbooks. Past exam papers are ideal as questions tend to get repeated from year to year, as well as giving a general guide as to the difficulty of the paper. Textbooks, however tend to have better worked solutions.

If you understand the equations and the material (not merely being able to recite them), then you ought to do well. Good luck.

Claude.
