| 1. | These different coordinates and corresponding basis vectors represent the same position vector.
|
| 2. | A position vector can be expressed as a linear combination of basis vectors:
|
| 3. | It points opposite to the position vector and perpendicular to the velocity vector.
|
| 4. | A position vector defines a point in space.
|
| 5. | The particles next position is calculated by adding its velocity vector to its position vector.
|
| 6. | The velocity may be equivalently defined as the time rate of change of the position vector.
|
| 7. | The position vector of the particle is
|
| 8. | Linear algebra allows for the abstraction of an " n "-dimensional position vector.
|
| 9. | A position vector may also be defined in terms of its magnitude and direction relative to the origin.
|
| 10. | If you average the position vectors of all human beings, you get a point inside the Earth.
