As part of the A level Physics course, students have to know different ways to measure “g”, one of the best-known numbers in Physics and Maths: 9.81 m/s2.
The class used light gates and dataloggers to measure the time for a card to fall a particular height, then by plotting a graph of height against time2 and calculating the gradient, they found their measured value of g.
