Physics SL

This course provides plenty of material for those curious about Physics, while challenging you to improve your analytical and mathematical skills.

Whiteboard from a lesson on conservation of momentum: two blocks before a collision, one of 3 kg moving at 2 metres per second and one of 5 kg at rest, combining into a single 8 kg block afterwards, with total momentum before set equal to total momentum after and solved to give 0.75 metres per second.
From a lesson: understanding the principle of conservation of momentum, and how it can be used in calculations.

Where the marks go

Six things that cost students the grade.

Physics at Standard Level rewards clear reasoning far more than it rewards memory. Students who treat it as a set of equations to memorise tend to plateau around a 4 or a 5, however hard they work.

  1. Space, time and motion

    Forces and free-body diagrams

    Knowing how to draw free-body diagrams and apply Newton’s laws to them is like a magic trick that unlocks a lot of marks in kinematics questions.

  2. Wave behaviour

    Constructive and destructive interference

    Every single exam has a question on this topic, yet students very often fail to understand the concepts properly.

  3. The particulate nature of matter

    Circuits

    Drawing circuit diagrams, understanding what potential difference is, and how energy works in an electrical circuit — these are key skills in this topic that are often lacking in students.

  4. Fields

    Magnetic fields

    Everyone has their own version of the hand rule, and it is common to not really grasp what is going on with it. Definitely one of the hardest topics in SL.

  5. Assessment

    Uncertainties and graphs

    Many students drop significant marks on Paper 1B, which is all about understanding experimental technique and uncertainties. Studying this as a separate topic really pays off.

  6. Assessment

    The Internal Assessment

    A fifth of the grade is for the IA, and a lot depends on how you choose your topic, and how you analyse the data. These are things that we can work on together to maximise your marks.

“He clearly has a deep understanding of both his subjects and the diploma… he helped me get two sevens in Physics and Maths AA SL.”
