Hooke’s Law Apparatus is a mechanical device used to demonstrate Hooke’s Law, which states that the extension of a spring is directly proportional to the force applied to it. The apparatus typically consists of a metal frame with a spring attached to one end and a scale attached to the other end. A weight hanger or load cell is used to apply a force to the spring, causing it to stretch or compress. The scale or a ruler is used to measure the extension of the spring, which is proportional to the applied force.
Hooke’s Law apparatus is commonly used in physics experiments and demonstrations, as well as in educational settings like high school and college science labs. It helps students understand the concept of elasticity and the relationship between force and displacement of an object.
