Mathematical requirements

  • In physics, maths is used as a tool to solve problems related to the relationships between quantities.
  • Without basic maths skills you could still understand some concepts but would not be able to solve problems.
  • Sometimes the language of maths is used to explain and describe not just perform calculations.
  • Qualitative descriptions of data include the direction and relationship in which two variables change (e.g. as time increases, distance increases proportionally).
  • Quantitative descriptions of data include numerical values (e.g. the speed of the object is 5ms-1).
  • Graphs are visual representations used to represent relationships.


  • Numbers

    In physics, data collected from experiments and answers to problems are rarely nice easy whole numbers. This page shows some of the considerations you should have when presenting a number. When writing down a value from an experiment, we should...

  • Pythagoras and trigonometry

    exercises and tutorials

  • Simultaneous equations

    Particularly useful when solving circuit problems using Kirchoff´s laws, how to solve for two unknowns when you have two equations.

  • Non-linear graphs

    Some common non linear graphs.

  • Linear graphs

    Interpreting the gradient and intercept of straight line graphs

  • Rearranging equations

    Demonstrations of some simple algebra involving rearranging equations.
