Hooke's law states that the length of extension or compression of the spring is done by the force directly proportional to it. Hooke’s Law was discovered by the scientist Robert Hooke in the year 1660. | Onheaven

What is Hooke's law? In this video, Professor Walter Lewin presents Hooke's law. Hooke's Law is a principle in physics stating that the force (F) needed to stretch or compress an elastic object (like a spring) is directly proportional to the distance (x) it's stretched or compressed from its resting position, expressed as F = k x, where k is the spring constant (stiffness). This relation holds within the material's elastic limit, meaning the object returns to its original shape after the force i
