FForce exerted by the spring

kSpring constant (stiffness)

xDisplacement from equilibrium

PE1/2 * k * x² (Potential Energy)

Overview

Hooke's Law states that the force needed to extend or compress a spring by some distance is proportional to that distance.

💡

Pro Tips

The formula is F = k * x.
A higher spring constant 'k' means the spring is stiffer.
This law is only valid within the elastic limit of the material.

Fun Facts

"Robert Hooke, a contemporary of Isaac Newton, first stated this law in 1676 as a Latin anagram."
"Hooke's Law is the foundation of many sensors, including bathroom scales and pressure transducers."
"Even seemingly solid objects like steel beams behave according to Hooke's Law under small loads."

Formula: F = k * x
