Physics Problems are divided into 5 major categories
1. Classical Mechanics
2. Thermodynamics
3. Waves and Oscillations
4. Electromagnetic
5. Modern Physics
If you realise, for each of these sub topics, there are just a
fixed number of equations. Hence, for each question (up till Uni
year 1 level), if you really really cannot do, just write out all
the equations in that sub topic, better still if you can further
sieved out the valid equations out beforehand.
With all the equations, decide which one will be able to come out
with an answer with the available data. Sometimes, after some
equations churned up some extra data, you can use these data, along
with the given ones, on other equations. In the end, your question
can be solved.
