In physics, the term for the change in position of an object over time is called displacement. Displacement measures the overall change in an object's position from its initial point to its final point, taking into account direction. It is a vector quantity and can be represented as a straight line between two points. Understanding displacement is fundamental in kinematics, as it relates to concepts such as velocity and acceleration. It is widely used in various fields, including physics, engineering, and even in everyday contexts like navigation.
