What term describes the rate at which an object changes position, including direction?

The term that describes the rate at which an object changes position, including direction, is velocity. Velocity is a vector quantity, which means it has both magnitude and direction. When measuring how quickly something moves, if we take into account the direction it is traveling, we refer to this as velocity rather than speed.

Speed, on the other hand, is a scalar quantity that only considers the magnitude of motion—how fast an object is moving, regardless of the direction.

Acceleration describes the rate at which an object changes its velocity, which could involve increasing speed, decreasing speed, or changing direction, but it is not about the rate of change of position itself.

Kinematics is the branch of physics that studies the motion of objects without considering the forces that cause the motion. It encompasses concepts such as displacement, velocity, and acceleration but does not itself refer to a specific rate or measurement. Thus, of all these terms, velocity is the one that accurately describes the change in position with direction included.
