1. What is a weighing scale and how does it work?A weighing scale is a tool that tells us how heavy something is. It can use a balance that swings to find equal forces, a spring that stretches to feel weight, or a digital sensor that turns force into an electric signal.
2. Why do we need weighing scales in everyday life?Weighing scales help make sure people pay the right amount for things, keep people healthy by measuring their weight, and help scientists and engineers design safe bridges and airplanes.

Metrology: The scientific study of measurement, including units, scales, and methods.
Fulcrum: The pivot point on which a lever, such as a beam balance, rests or turns.
Transducer: A device that converts energy from one form to another, such as force to an electrical signal.
Hooke's Law: States that the force needed to extend or compress a spring is proportional to the distance it is stretched or compressed.
