The video tutorial explains the working principle of a spring balance, which is used to measure the weight of objects. It operates based on Hooke's Law, stating that the elongation of a spring is directly proportional to the load applied. The video details the components of a spring balance, including a steel spring, a hook, and a scale. It describes how the balance measures weight by balancing gravitational and spring forces, with the scale marked in Newtons and grams. The tutorial concludes with a summary of the spring balance's function and principles.
