19N.3.SL.TZ0.1d

A student investigates how the period T of a simple pendulum varies with the maximum speed v of the pendulum’s bob by releasing the pendulum from rest from different initial angles. A graph of the variation of T with v is plotted.

(d)

The lines of the minimum and maximum gradient are shown.

Estimate the absolute uncertainty in a.
