# __MCQ on Distance and Displacement__:

- Displacement: The directed line segment of an object doing mechanical movement from the initial position to the end position, its size has nothing to do with the path, and the direction is from the start point to the endpoint. It is a physical quantity with magnitude and direction, that is, a vector.
- Distance is the length of the object's motion trajectory, which is a scalar.
- Displacement is a vector, and its size is only related to the position of the starting point and the ending point of the movement and has nothing to do with the actual path experienced by the object movement.
- The distance is a scalar, and the size is related to the path that the object moves through.
- Displacement is a physical quantity that describes the size and direction of the position change of an object.
- It is a directed line segment of a moving object from the initial position to the final position. Displacement has both magnitude and direction and is a vector.
- The magnitude is only related to the position of the starting point and the ending point of the movement and has nothing to do with the actual path that the object moves through.
- The distance is the length of the path that the object moves through, which is a scalar, and the size is related to the path that the object moves through.
- Displacement and distance are both process quantities, and both displacement and distance of object motion need to go through a period.
- In terms of size, in general, the size of the displacement is smaller than the distance. Only in a unidirectional linear motion, the size of the displacement is equal to the distance.
