Hooke's Law Concept

Demonstrations in Hooke's Law

Side-by-side comparison of the Hooke's Law setup: left panel shows unloaded springs hanging from a horizontal rod with a meter stick and Ohaus mass set below; right panel shows the same springs loaded with brass masses at varying extensions

Hooke's Law

Verifies Hooke's Law by hanging masses from springs and measuring extension. Comparing springs with different spring constants shows that is a property of the specific spring, and the linear force-displacement …

Stiff Springs

A spring with a very large spring constant demonstrates what "stiff" means quantitatively. Three kilograms stretches it only about an inch, and it cannot be fully compressed by hand — …
Stand with three spring configurations loaded with identical brass masses: two pink springs in series (left), single pink spring (center), two dark red springs in parallel (right), with meter stick for measuring displacement

Series and Parallel Springs

Hang identical masses from single, series, and parallel spring configurations to show how effective spring constants combine. Students see that series springs stretch more and parallel springs stretch less than …
