31. Then for a medium with mean velocity vector "'V "', the dispersion relationship with Doppler shift becomes: 32. In the case of a frame, the angular velocity vector is over the instantaneous axis of rotation. 33. The index r / l on the coefficients A and B denotes the direction of the velocity vector . 34. For example, the space shuttle targets an altitude, velocity vector , and gamma to drive main engine cut off. 35. As it is a Hodge dual vector, which is precisely the previous angular velocity vector \ vec \ omega: 36. But the forces are generated by the pressure distribution on the body, and are referred to the velocity vector . 37. Basically, I have a 2D square grid and a velocity vector field with known values on the grid points. 38. The motion of an object moving in three-dimensional space is characterized by a position vector and a velocity vector . 39. The point of connection of the pendulum moves with the surface velocity vectors of the Earth at that latitude. 40. An example of such a constraint is a rolling wheel or knife-edge that constrains the direction of the velocity vector .
