Edexcel IGCSE Physics Analyse Data and Conclusions
Edexcel IGCSE Physics syllabusPhysics 4PH1Issue 4 (2024)

Practise Edexcel IGCSE Physics data analysis by spotting anomalies, describing graph relationships and testing conclusions against plotted data.

How this is tested

  • Circle or identify anomalous points on a graph before using the trend.
  • Describe graph relationships, including increasing trends and changing rates.
  • Evaluate proportionality or inverse claims by checking constants from graph data.

Question 10(c)(iv)

[Maximum number: 2]

Diagram 1 shows the apparatus a student uses to investigate the bending of a wooden strip.

Part of the wooden strip is clamped to a table.
A load is fixed to the free end of the wooden strip, causing it to bend.

Diagram 1

Diagram 1

The free end of the wooden strip is positioned a length, L , beyond the edge of the table, as shown in diagram 1.

The weight of the load causes the end of the wooden strip to move down through a height, h.

A student investigates how the length, L , affects the height, h .

The table shows the results of the investigation.

Table for Question 10(c)(iv) — Edexcel IGCSE Physics

The student concludes that h is directly proportional to L .

Evaluate the student's conclusion.
