11. Nonholonomic constraints depend on the particle velocities , accelerations, or higher derivatives of position. 12. And as interference decreases, so does the phase difference between sound pressure and particle velocity . 13. The official designation was G-009 : Purdue University-Geotropism, Fluid Dynamics and Nuclear Particle Velocity . 14. A p-u type of sound intensity probe measured both the sound pressure and the particle velocity directly. 15. The wave moves relatively fast, while the particles oscillate around their original position with a relatively small particle velocity . 16. In applications involving sound, the particle velocity is usually measured using a logarithmic decibel scale called particle velocity level. 17. In applications involving sound, the particle velocity is usually measured using a logarithmic decibel scale called particle velocity level. 18. The radiation propagates with a characteristic angle with respect to the particle track, which depends on the particle velocity . 19. For this reason the bigger the synchrotron, the less input energy it needs to attain a given particle velocity . 20. With the substitution of pressure for voltage, and volume particle velocity for current, the equations are essentially the same.
