Answer 1

• It consists of a spring fixed at one end with a hook to attach an object at the other.
• It works by Hooke's Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position.
• Therefore, the scale markings on the spring balance are equally spaced.
