IB Physics Tutoring: HL and SL

Start by sketching the situation and stating the quantity you need. Mark directions and distinguish values given in the question from quantities you have to calculate. Before substituting numbers, say why the chosen relationship applies. Is acceleration assumed constant? Is energy transferred to the surroundings? Is the value an average or an instantaneous quantity?

For a velocity–time graph, the slope and the area answer different questions. Treating the graph as a picture of the object's path can send the entire solution in the wrong direction. We can work through how to read one interval, label the units, and explain the result in words. You then try a changed graph to test whether you can make the distinction independently.

The Physics scientific investigation contributes 20% of the final grade. Research design, data analysis, conclusion and evaluation each carry up to six marks. A focused question helps you plan relevant evidence, but the quality of the method, analysis and explanation also matters; a narrow question alone does not determine the mark.

In tutoring, we can review how you collected or selected data, how uncertainty affects your analysis, and whether the conclusion follows from the evidence. For a graph, discuss what the gradient represents, its units and the limitations of the fitted relationship. A straight line does not by itself establish a perfect relationship. Explain how a specific limitation affects your conclusion and how an improvement would address it.

Paper 1A uses multiple-choice questions, while Paper 1B asks you to work with data. Paper 2 includes short-answer and extended-response questions. In tutoring, practise choosing an appropriate model, reading tables and graphs, and writing reasoning another reader can follow. When reviewing a multiple-choice answer, explain why the other options fail rather than remembering the selected letter.

Review an attempted answer by identifying where the reasoning first went wrong. An incorrect final value may come from a mistaken sign, a unit conversion or an inappropriate model. Repeating a whole question set without isolating that cause can hide the gap. In a written response, show the relationship, substitutions and units, then check whether the magnitude and direction make sense for the situation.
