2. n Set-up steps n Solving steps n Check-up steps

3. Set-up Steps n Work in pencil on rough work sheet because you may make mistakes at the beginning n Read the question very carefully n Read the question once more if you do not understand it well

4. Set-up Steps n Circle or underline keywords and important information, e.g. upwards, downwards, left, right, approaching, parallel, perpendicular, constant, reflected, neglected etc.

5. Set-up Steps n Identify all the given quantity and unknowns n Think about the physical law related to these quantities n Try to transform the given information like diagrams and graphs into mathematical equations

6. Set-up Steps n Note all the given assumptions,e.g. no energy loss, no air resistance, no intermolecular force etc. n Recall some similar problems you have solved before. n Quote the formulae that seem helpful

7. Solving steps n Divide the problem into parts n Solve algebraically first n Check all units in your calculation n Do not miss the ‘+’ or ‘-’ signs n Consider whether the answer you get is reasonable or not

8. Check-up steps n Reread the question and make sure that you have not misinterpreted it. n Check the diagrams or graphs (if any) to see whether the points (crosses) are correctly plotted, and whether the scales are clear and the axes labelled with correct units n Check all units in your calculation n Do not miss the ‘+’ or ‘-’ signs n Consider whether the answer you get is reasonable or not

9. Check-up steps n Check the calculation n Check whether your answer fulfills the requirement of the question n Check whether you have corrected the answer to 3 significant figures and have not left out the unit

10. Check-up steps n If you cannot get the answer, it is very probable that you have 1. Made careless mistakes 2. Not clearly identified the relationship among the variables, unknowns and physical objects 3. Drawn diagrams or graphs wrongly 4. Missed some given information 5. Failed to recognize certain principles and laws which cannot be applied in that particular situation
