A reference point is a specific location or object used to determine the position or movement of something else. It serves as a baseline for measuring distance, direction, or change. For example, when navigating, a person might use a landmark, like a tree or a building, as a reference point to find their way. In physics, reference points are crucial for understanding motion. An object’s position is often described in relation to a reference point, such as the ground or a coordinate system. This helps in analyzing how far and in what direction an object moves from that point.
