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
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:
$$\boxed{\text{The object is not moving at all here. It is staying at 4 meters from 0 to 3 seconds.}}$$
