Practise Edexcel IGCSE Physics communicating experimental findings by drawing straight or curved best-fit lines that represent plotted data.

How this is tested

  • Draw a straight line of best fit through the origin and non-anomalous plotted points.
  • Draw a smooth curve of best fit with data points distributed evenly around the curve.

Question 10(c)(iii)

[Maximum number: 1]

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.
