Determine g with a simple pendulum
Measure how the period of a pendulum depends on its length, plot a straight-line graph, and use its gradient to find the gravitational field strength, with its uncertainty.
Choose how much help you want
Every dataset code gives a slightly different pendulum. Share a code with a classmate to get the same apparatus.

Drag the two gold handles to place your line of best fit.
Read the metre rule
The rule's zero is level with the bottom of the clamp. Each small division is 1 mm.
Read to the centre of the bob, not its top or bottom. The dashed line marks the centre.
