This diagram covers Displacement Method Visualised within Density for GCSE Physics. Revise Density in Particle Model for GCSE Physics with 13 exam-style questions and 30 flashcards. This topic shows up very often in GCSE exams, so students should be able to explain it clearly, not just recognise the term. It is section 5 of 13 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.

📊 Displacement Method Visualised

Eureka can (overflow can) filled with glowing blue water. A rock on a string is lowered into the water, causing water to overflow through the spout into a measuring cylinder below. The displaced water volume equals the rock's volume.

Figure 1: Eureka can method — the volume of water displaced into the measuring cylinder equals the volume of the irregular solid.
