graphical analysis of motion\npart 1: concepts:\n1. the graph below shows the position vs time for an object in motion. give a description of what the object is doing during each of the intervals listed in the table below:\nposition (m)\ntime (s)\nregion start time (s) end time (s) description of motion\na\nb\nc\nd\ne\nf
Answer
Explanation:
Step1: Analyze Region A
The position - time graph is curved upwards. The slope of the position - time graph represents velocity. As the slope is increasing, the object is accelerating in the positive direction.
Step2: Analyze Region B
The graph is a straight - line with a constant positive slope. So, the object is moving with a constant positive velocity.
Step3: Analyze Region C
The slope of the graph is decreasing. This means the object is still moving in the positive direction but is decelerating.
Step4: Analyze Region D
The slope of the graph is zero. So, the object is at rest.
Step5: Analyze Region E
The slope of the graph is zero. The object remains at rest.
Step6: Analyze Region F
The graph has a negative slope. The object is moving in the negative direction with a constant velocity.
Answer:
| Region | Start Time (s) | End Time (s) | Description of Motion |
|---|---|---|---|
| A | 0 | 2 | Accelerating in positive direction |
| B | 2 | 4 | Moving with constant positive velocity |
| C | 4 | 6 | Decelerating while moving in positive direction |
| D | 6 | 7 | At rest |
| E | 7 | 8 | At rest |
| F | 8 | 10 | Moving with constant negative velocity |
