Which of the following refers to objects that are moving or free-standing during an investigation?

The term that refers to objects that are moving or free-standing during an investigation is "unfixed objects." Unfixed objects are not secured or anchored, making them subject to movement due to external forces or interactions. In investigative contexts, such as crime scenes or accident reconstructions, unfixed objects can alter the scene or evidence if they are disturbed. This is crucial for forensic professionals as it emphasizes the importance of maintaining the integrity of the scene until the investigation is complete.

In contrast, fixed objects are those that are secured in place and do not move, which helps in providing a stable reference for the investigation. Featureless objects typically lack distinguishable characteristics, and permanent objects might refer to items that are either fixed or established over time but do not specifically capture the idea of being free-standing or moving.
