Final answer:
In physics, 'record' and 'non-record' can be used to describe distance and displacement. An object can have a recorded distance of zero but a non-zero displacement, or vice versa, depending on its path. Similar to how printed books allow for record-making through notes and an audio book doesn't, despite both delivering the author's content.
Step-by-step explanation:
The terms record and non-record can be used to describe the movement of an object in physics, particularly when discussing distance and displacement. For instance:
- a. An object may record a distance of zero while recording a non-zero displacement. This situation occurs when the object starts and ends at the same position, making the total distance traveled zero, but the displacement, which is the shortest path between the start and end points, is non-zero due to the direction of travel.
- b. An object may record a non-zero distance while recording a displacement of zero. This can happen if the object moves in a closed loop, returning to the starting point. The distance traveled is the total length of the path taken, which is not zero, but the displacement is zero because the start and finish points are the same, resulting in no overall change in position.
Comparing this to a printed book and an audio book, one may say that a printed book allows for record-making through marginal notes or highlights, whereas an audio book does not permit this. However, both mediums deliver the author's material to the reader or listener, respectively.
