Worked Solution & Example Answer:A student suspended a spring from a laboratory stand and then hung a weight from the spring - AQA - GCSE Physics - Question 1 - 2018 - Paper 1
Step 1
Step 2
Before taking any measurements, the student adjusted the ruler to make it vertical. Explain why adjusting the ruler was important.
Answer
Adjusting the ruler to make it vertical is important to reduce error in measuring the extension of the spring. If the ruler is at an angle, the measured extensions may appear shorter, leading to inaccurate data collection.
Step 3
Step 4
Why does the data plotted in Figure 3 support the student's prediction?
Answer
The data plotted in Figure 3 supports the student's prediction by showing a consistent trend where the extension of the spring increases linearly with the increase in weight, indicating that the spring follows Hooke's Law up to its elastic limit.
Step 5
What can you conclude from Figure 4 about the deformation of the spring?
Answer
From Figure 4, it can be concluded that the spring exhibits elastic deformation as the weights increase. Once the weights are removed, the spring returns to its original position, suggesting that it has not exceeded its elastic limit during the investigation.
