This is a series of slides to help discuss the general process of solving physics problems.

The most important part is to read the question. This sounds funny, but you might need to read the problem several times to be sure you understand what the problem states.

Now that you have read the problem you need to think. What is the problem about? Energy? Momentum? What general physics principle is being addressed.

To help you conceptualize the problem you should draw a picture. It doesn't have to be good. Just some circles and lines. A sketch so that you can think more deeply about the content of the question.

Once you have drawn the picture you can identify the variables that are stated in the problem or known already as universal constants. Label these variables on your diagram. It is also helpful to identify the variable you are solving for.

Once you have understood the problem and identified the variables you should consider the relationships that are defined by formulas and choose a formula that is related to this particular problem

Put the variables into the equation. Are there numbers or are you supposed to generate a new relationship? Use the principles of algebra to isolate the unknown variable and solve it.

When you have calculated the answer either using your calculator or by hand, think again. Does this answer make sense? Did you wind up with the correct units for the answer? Think.
