A teacher gathered data during an unknown experiment. The class was asked to analyze the data, and to describe the motion of the object.

Based on the information in the table shown above, how should the students most logically describe the object’s motion?
The object’s speed is decreasing from 2 s to 6 s.
The object is moving at a constant speed.
The object is at rest.
The object’s average speed is 0.125 m/s.
The students should most logically describe the object's motion as: "The object's speed is decreasing from 2 s to 6 s." This is because the velocity (which includes the direction of motion) is changing during this time period, indicating a change in speed. The data shows that the object travels more distance in the first 2 seconds than it does in the next 4 seconds, which means it is slowing down. Therefore, the correct answer is the first option.
To determine the motion of the object based on the information in the table, we need to analyze the data provided. Looking at the first column of the table, we can see that the time intervals increase in equal increments from 2 seconds to 6 seconds. However, the corresponding distances traveled decrease with each time interval. This suggests that the object's speed is decreasing.
Therefore, the most logical description of the object's motion is:
The object's speed is decreasing from 2 s to 6 s.
