Comparing materials fairly

Comparing materials fairly

Vertical Young modulus experiment showing a clamped wire with labelled length L, diameter d, extension delta L, area inset, and a hanging mass causing tensile force F Young modulus tells you how stiff a material is, not how stiff one particular wire happens to be. A thick steel cable and a thin steel string can stretch very differently under the same load, but the material can still have one Young modulus.

The Young modulus Lesson

  1. A Level
  2. /Physics
  3. /The Young modulus

Step-by-step lessons on AQA A Level Physics The Young modulus. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
