💡 What is an extension spring used for in a physics classroom to demonstrate Hooke's Law and energy storage?

In short, extension springs are handy for hands-on measurement of force versus displacement and exploring how elastic energy builds as they stretch.

• Hooke's Law demonstrations with calibrated masses and measured extension
• Elastic potential energy calculations during spring-mass experiments
• Safe, repeatable lab setups for physics, engineering, and STEM activities
