Weight is the measure of how heavy an object is due to the force of gravity acting on it. It tells us how much matter is in an object, which is often measured in units like pounds or kilograms. For example, a bag of flour might weigh 5 kilograms, meaning gravity pulls it down with that force. Different objects have different weights based on their size and material. For instance, a feather is much lighter than a rock because it has less mass. Understanding weight helps us in everyday life, like when we need to lift something or calculate how much food to buy for a party.
