Position, displacement and distance
In order to describe the movement of the object, we must learn to describe its position - where it is in every specific point in time. More precisely, we must determine its position relative to a certain reference system. If the object moves relative to the reference system, for example, if the passenger went into the tail of the aircraft, then we say that the position of the object has changed. Changing the position is called moving. The term movement implies that the object has moved or moved. The distance is defined as the movement value between two points. Please note that the distance between the two points and the distance traveled is different things.
