CAPE Physics Unit 1 · 2008 · Paper 2 · Question 1(a)

A steel ball bearing falls from rest, and its distance (y) and time (t) are measured using electronic timing. The data is provided in Table 1.

Use the data to plot a suitable straight line graph (on page 5) to determine the value of, g, the acceleration of free fall.

This question uses a figure or table from the paper — you'll see it when you practise.
