Transcribed Image Text:### Motion Diagrams: Understanding Scenarios
The image provided shows a motion diagram that represents an object's movement through 11 points, labelled from 0 to 10, where the object moves from point 0 to point 10. The spacing between points indicates changes in speed.
#### Diagram Description:
- **Points on the Diagram**: The diagram consists of 11 black circles (points), each numbered from 10 to 0.
- **Spacing between Points**: The spacing between the points decreases steadily from left to right.
#### Interpretation of the Diagram:
The decreasing distance between the points suggests that the object is decelerating as it moves from point 0 to point 10.
### Multiple Choice Question:
The motion diagram below represents which of the following scenarios? (Motion starts from point 0 to point 10)
1. **Charlie is driving on cruise control when he sees the light ahead turn red, so he slows down**
- This scenario fits the diagram because it describes a continuous deceleration, which is evident from the decreasing spacing between the points.
2. **Not enough information**
- This option is invalid because the diagram provides clear information about the object's deceleration.
3. **Bob goes for a jog at a constant pace**
- This scenario is incorrect because a constant pace would result in equal spacing between the points throughout the motion.
4. **Alice starts her car and begins driving to school, accelerating to a cruising speed**
- This scenario doesn't fit because the diagram shows deceleration, not acceleration. The points would get further apart if the object were accelerating.
### Answer:
The diagram represents **Charlie is driving on cruise control when he sees the light ahead turn red, so he slows down**. This is identified due to the progressively shorter distances between each successive point, indicating a decrease in speed.
