Free A-Level Physics practical tools

Interactive instrument simulators for practising the measuring skills assessed in A-Level Physics required practicals. They're free to use, with no sign-up.

• Micrometer screw gauge simulator

  An interactive micrometer screw gauge for learning to read the sleeve and thimble scales to 0.01 mm.

  Used in: Resistivity of a Wire, Young Modulus of a Wire

• Vernier caliper simulator

  An interactive vernier caliper for learning to read the main and vernier scales to 0.1 mm.

  Used in: Young's Double Slits

• Analogue meter reading practice

  Practise reading analogue ammeters and voltmeters on different ranges, to the nearest half division.

  Used in: EMF and Internal Resistance, Resistivity of a Wire, Capacitor Discharge

• Measuring cylinder and meniscus reading practice

  Practise reading the volume in a measuring cylinder at the bottom of the meniscus, on cylinders with different scales.

  Used in: Boyle's Law, Charles's Law

• Percentage uncertainty calculator

  Convert between absolute and percentage uncertainty, and combine uncertainties for sums, products, quotients and powers, with the working shown.

• Multimeter simulator

  A digital multimeter to practise choosing the right function and range, reading the display, and converting the units and prefixes.

  Used in: EMF and Internal Resistance, Resistivity of a Wire

These tools are part of LabWizard, which takes students through full simulated required practicals, from measurement to graphing, analysis and exam questions.
