Spring Scale

A spring scale is a device that measures force, such as weight or tension, by utilizing the elongation of a stretched spring. When an object is hung from the scale, the gravity pulls on it, causing the spring inside to stretch proportionally to the force exerted. The scale has markings that correspond to the amount of stretch, which can be read as the object's weight or force. Spring scales are simple, reliable tools commonly used in laboratories, kitchens, and industries to measure weights accurately without complex machinery.
