What describes the change in the position of an object in a specific direction?

• A. Distance
• B. Velocity
• C. Displacement
• D. Speed

Answer: (C)

Displacement describes the change in position of an object in a specific direction. It is a vector quantity, which means it has both magnitude and direction. When calculating displacement, you consider the straight-line distance between the initial position and the final position of the object along with the direction from the starting point to the endpoint. This makes displacement particularly useful in physics for understanding not just how far an object has moved, but also the direction of that movement, which provides deeper insight into the object's motion. In contrast, distance measures how much ground an object has covered during its motion, regardless of direction, focusing solely on the total path length. Velocity, while it also describes motion, refers to the rate of change of displacement over time rather than the displacement itself. Speed simply measures how fast an object is moving without any reference to direction, making it a scalar quantity. Therefore, the defining characteristic of displacement is its directional aspect combined with the measurement of the straight-line change in position, solidifying it as the accurate description of the movement in terms of direction.
