Distance refers to the amount of space between two points. It can be measured in various units, such as meters, kilometers, miles, or feet. In everyday life, we often think of distance when considering how far we need to travel to reach a destination, like a friend's house or a store. In physics, distance is a scalar quantity, meaning it only has magnitude and no direction. It is different from displacement, which measures the shortest path between two points and includes direction. Understanding distance is essential in fields like geometry, navigation, and physics.
