Paper 2 H - SAMPLE SET 1 Q1 Answers
1) A student suspended a spring from a laboratory stand and then hung a weight from the spring.
Figure 1 shows the spring before and after the weight is added.
Figure 1 shows the spring before and after the weight is added.
1.1) Measure the extension of the spring shown in Figure 1. [1 mark]
Extension = _________ mm
The student used the spring, a set of weights and a ruler to investigate how the extension of the spring depended on the weight hanging from the spring.
Before starting the investigation the student wrote the following prediction:
Before starting the investigation the student wrote the following prediction:
|
The extension of the spring will be directly proportional to the weight hanging from the spring.
|
Figure 2 shows how the student arranged the apparatus.
1.2) Before taking any measurements, the student adjusted the ruler to make it vertical.
Explain why adjusting the ruler was important. [2 marks]
The student measured the extension of the spring using a range of weights.
The student’s data is shown plotted as a graph in Figure 3.

1.3) What range of weight did the student use? [1 mark]
1.4) Why does the data plotted in Figure 3 support the student’s prediction? [1 mark]
1.5) Describe one technique that you could have used to improve the accuracy of the measurements taken by the student. [2 marks]
1.6) The student continued the investigation by increasing the range of weights added to the spring.
All of the data is shown plotted as a graph in Figure 4.
