K.C.S.E Physics Q & A - MODEL 2019PP1QN14
(a) A student is provided with five 20g masses, a meter rule, a spring with a pointer, a stand a boss and a clamp.
(i) In the space provided, sketch a labelled diagram of the set up that may be used in order to verify Hooke’s law using these apparatus.
(ii) State two measurements that should be recorded in order to plot a suitable graph so as to verify Hooke’s law.
(iii) Describe how the measurements made in (ii) can be used to determine the spring constant.
(b) A helical spring stretches by 0.6cm when Supporting a weight of 40 g. Determine the extension when the same spring Supports a weight of 65 g.

Figure 5 shows two springs C and D of the same length and equal number of turns made from the same wire.
State with a reason which of the two springs can support a heavier load before attaining the elastic limit.

Figure 8 shows the graph of extension against force for a certain helical spring.
On the same diagram sketch the graph of extension against force for a spring with a lower value of spring constant.
K.C.S.E Physics Q & A - MODEL 2017PP1QN15
(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;
