Materials
This unit investigates the mechanical properties of materials, including stress, strain, elasticity, and strength. Students learn how materials respond to forces, analyze experimental data, and connect theory with practical applications in engineering and physics.
Key Concepts
Springs & Hooke’s Law
Elastic Potential Energy
Deforming Materials
Stress–Strain & Young’s Modulus
The Evolution of Materials
Two million years ago the stone age began, where men made tools and weapons out of stone that allowed them to hunt and/or defend themselves from large animals. Around 1700 BC the Chinese learned how to combine copper and tin to build stronger tools/weapons out of bronze. The heralding of a new age brought with it the need for miners and lots of new jobs – this was the start of organised labour.
The Europeans began developing even stronger tools and weapons out of Iron around 1200 BC, which sparked another technological leap and a myriad of advances for civilization. Time and time again the discovery of new “wonder-materials” proved to be societal game-changes: glass (windows to bottles); steel (skyscrapers to spoons); aluminium (tin cans to outer space); plastics (packaging to pollution); silicon (computers to smart watches).
