Analysing Scientific Investigation

Question 1 : Lembaga Peperiksaan Malaysia

A student carries out an experiment to find out the relationship between the change in length , y , of
a spring and mass, m , of the load on the spring. The arrangement of the apparatus for the experiment
is shown in Figure 1 . The length of the spring when a load is placed on the piston is l .

At the beginning of the experiment there is no load. The length of the spring is lo . The actual length
of lo is shown in Figure 2. The experiment is repeated by using load with mass , m , equal to 0.5 kg ,
1.0 kg , 1.5 kg , 2.0 kg and 2.5 kg. The actual lengths of the spring when the different masses are used
are shown in Figure 3, Figure 4, Figure 5, Figure 6 and Figure 7 on page 2.

(a) Based on the aim and the procedure of the experiment state the:

(i) manipulated variable

(d) On the graph paper on page 4 , plot a graph of y against m. [5 marks]

(e) Based on your graph, state the relationship between y and m .
