  • Propagate absolute and percentage uncertainties across addition, multiplication, and power relationships
  • Structure experimental data tables with consistent decimal places and slash unit headers
  • Plot graphs satisfying the 50% grid coverage rule and calculate gradients using large triangles
  • Score full marks on the Question 2(f) evaluation matrix by pairing specific limitations with physical improvements

Requirements

  • Enrolled in Cambridge AS Level Physics (9702)
  • Familiarity with basic laboratory equipment (rulers, stopwatches, meters)
