 Form 2 Physics Video Questions and Answers on Hooke's Law

(a) A student was provided with several identical masses, a metre rule, a spring and a stand, boss and clamp. Outline five steps that the student should
follow in order to verify Hooke’s law.
(b) Figure 4 shows a graph that was drawn from the results obtained in an experiment to study the extension of a spring. From the graph, determine:
(i) The spring constant k
(ii) The load that causes an extension of 3 x #10^-2# m.
