What Is Weight?
Weight measures how heavy something is due to gravity pulling on its mass. Think of it like how much force you feel when you hold something - a heavy book feels heavier than a light pen because it has more mass. Understanding weight helps us with everything from cooking and fitness to shipping and science experiments.
