Calculating Uncertainties | AQA A Level Physics Revision Notes 2017
Nov 20, 2023 · Percentage Uncertainty: where uncertainty is given as a percentage of the measurement. To find uncertainties in different situations: The uncertainty in a reading: ± half the smallest division. The uncertainty in a measurement: at least ±1 smallest division.
You can reduce uncertainty by fixing one end of a ruler as only the uncertainty in one reading is included. You can also reduce uncertainty by measuring multiple instances, E.g.to find the time for 1 swing of a pendulum, measure the time for 10 e.g. 10 swings in.
