Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the earliest known metal springs?Used by ancient Greeks and Romans, circa 500 BC
2. What is the governing principle?Hooke's Law (F = -kx), relating force to displacement
3. What is a spring and how does it work?A spring is a coiled metal that can stretch or squish and then bounce back. When you push or pull it, it stores energy, and when the force is removed, it releases that energy to return to its original shape.
4. Why were springs first made by the Greeks and Romans?The Greeks and Romans made metal springs around 500 BC using bronze and iron. They used them for toys, traps, and early clockwork devices.

Elastic Limit: The maximum stress a material can withstand before permanent deformation occurs.
Spring Constant (k): A measure of a spring's stiffness; the force required to stretch or compress it by one unit.
Young's Modulus: A measure of a material's stiffness or resistance to elastic deformation under tensile or compressive stress.
