1.22 Force-extension practical
Practical: investigate how extension varies with applied force for helical springs, metal wires and rubber bands
Concept essentials
- Force is measured in newtons using a newton meter or an equivalent force method.
- Extension is the increase in length after a force is applied.
- A fair force-extension practical changes the applied force while measuring the resulting stretch.
- Springs, metal wires and rubber bands can show different force-extension patterns.
