Weights, often referred to as mass, measure the amount of matter in an object. It is commonly expressed in units such as grams, kilograms, or pounds. The weight of an object can change depending on the gravitational force acting on it, but its mass remains constant regardless of location. In everyday life, we encounter weights in various forms, such as food items on a scale or dumbbells in a gym. Understanding mass is essential in fields like science, engineering, and nutrition, as it helps us quantify and compare the physical properties of different objects.
