AH - g by Rolling Ball Kit
A set of 7 curved tracks that a pool ball rolls on. The period and curvature can be used to determine g.
This method is pupil friendly as the Physics is basically the same as the simple pendulum plus the energy spent on rolling. It has the advantage over a simple pendulum that there is no string that might stretch but on the other hand there is much more friction.
This method is a larger scale version of the ball bearing on a convex mirror or lens. It has the advantage of being more durable, does not require an expensive spherometer and the range of tracks allow for graphical approachs to be used which is strongly preferred by the SQA.
The approximate radius of curvature for each track is specified on the tracks and a method for pupils to determine that for themselves using only a ruler is discussed in the manual.
As part of a range of methods this slightly rougher method is ideal for pupils to evaluate.
