| 11. | The velocity triangles are constructed using these various velocity vectors.
|
| 12. | Actually, the velocity vector V's magnitude | V | can be any fractional component.
|
| 13. | This angular motion is quantified by the angular velocity vector.
|
| 14. | Only sound with parallel collinear phase velocity vectors interfere to produce this nonlinear effect.
|
| 15. | In-plane and out-of-plane direction is determined by the orbital velocity vector of the system.
|
| 16. | If a disk spins counterclockwise as seen from above, its angular velocity vector points upwards.
|
| 17. | The particles next position is calculated by adding its velocity vector to its position vector.
|
| 18. | Its velocity vector changes over time, in response to the forces acting on the particle.
|
| 19. | In the limit, pure translation becomes planar movement with point velocity vectors that are parallel.
|
| 20. | :Air resistance always acts in the opposite direction to the velocity vector of the projectile.
