| 1. | From the definition, it is clear that a displacement vector is a polar vector.
|
| 2. | Continuing this way, it is straightforward to classify any vector as either a pseudovector or polar vector.
|
| 3. | A number of quantities in physics behave as pseudovectors rather than polar vectors, including magnetic field and angular velocity.
|
| 4. | With cylindrical co-ordinates, the motion is best described in polar form with components that resemble polar vectors.
|
| 5. | This is an example of a general theorem : The curl of a polar vector is a pseudovector, and vice versa.
|
| 6. | Ordinary vectors are sometimes called " true vectors " or " polar vectors " to distinguish them from pseudovectors.
|
| 7. | The axis of a " binary " ( 180?) rotation quaternion corresponds to the direction of the represented polar vector in such a case.
|
| 8. | The velocity vector is a displacement vector ( a polar vector ) divided by time ( a scalar ), so is also a polar vector.
|
| 9. | The velocity vector is a displacement vector ( a polar vector ) divided by time ( a scalar ), so is also a polar vector.
|
| 10. | Likewise, the momentum vector is the velocity vector ( a polar vector ) times mass ( a scalar ), so is a polar vector.
