(Negative Average Velocity) Homework

In summary, negative average velocity is a measure of an object's average rate of movement in the opposite direction of a reference point. It is calculated by dividing the change in displacement by the change in time and represents constant movement away from the reference point. However, an object can have a negative average velocity and still be moving in a positive direction if the reference point is chosen in the opposite direction of the actual movement. Negative average velocity is interpreted as constant movement at a negative speed in the opposite direction of the reference point.

The sign would normally imply a direction but it's not clear to me which direction the problem statement considers to be +ve. It could be east or west for example.

Is that the problem statement as written? If it is then I think it's badly worded but I would take +ve to be north because it says "[+]28.5Km north of jollitown".

That would mean a negative velocity would be heading south.
 

1. What is negative average velocity?

Negative average velocity is a measure of the average rate at which an object moves in the opposite direction of a reference point. It indicates that the object is moving in the opposite direction of the reference point at a constant rate.

2. How is negative average velocity calculated?

Negative average velocity is calculated by dividing the change in displacement of an object by the change in time. The result will be negative if the displacement is in the opposite direction of the reference point.

3. What does a negative average velocity value represent?

A negative average velocity value represents that an object is moving in the opposite direction of the reference point at a constant rate. This means that the object is moving away from the reference point.

4. Can an object have a negative average velocity and still be moving in a positive direction?

Yes, an object can have a negative average velocity and still be moving in a positive direction. This can happen if the object is moving away from the reference point, but the reference point is chosen to be in the opposite direction of the actual movement.

5. How is negative average velocity interpreted in terms of speed and direction?

Negative average velocity indicates that an object is moving at a constant speed in the opposite direction of the reference point. This means that the object is traveling with a negative speed, which is equivalent to saying that it is moving at a constant rate in the opposite direction.
