QuestionMULTIPLE CHOICE QUESTION
A flat line on a distance/time graph means that
The object moved 4 meters in 3 seconds.
The object is moving at a constant rate
The object is not moving at all here. It is staying at 4 meters from 0 to 3 seconds.
Acceleration is constant here.
Studdy Solution
STEP 1
1. A distance/time graph plots distance on the vertical axis and time on the horizontal axis.
2. A flat line on this graph indicates no change in distance over time.
STEP 2
1. Understand the meaning of a flat line on a distance/time graph.
2. Evaluate each multiple-choice option based on the understanding from step 1.
STEP 3
A flat line on a distance/time graph indicates that the distance is not changing as time progresses. This means the object is stationary during this period.
STEP 4
Evaluate the options:
- **Option 1**: "The object moved 4 meters in 3 seconds."
- This implies a change in distance, which contradicts a flat line. Therefore, this is incorrect.
- **Option 2**: "The object is moving at a constant rate."
- A constant rate would imply a non-zero slope, not a flat line. Therefore, this is incorrect.
- **Option 3**: "The object is not moving at all here. It is staying at 4 meters from 0 to 3 seconds."
- This correctly describes a flat line, where the object remains at a constant distance. Therefore, this is correct.
- **Option 4**: "Acceleration is constant here."
- A flat line indicates no movement, hence no acceleration. Therefore, this is incorrect.
The correct answer is:
