Trajectory of projectile

Trajectories of projectiles impinging on a target for reactions below the barrier left), where only elastic scattering occurs and above the barrier right), where the more central trajectories are absorbed. As is seen, nuclear reactions will necessarily decrease the large angle fraction of elastically scattered projectiles...

Overspin (Overstabilization). In a spin stabilized projectile, when the rate of spin is too great for the particular design of projectile, it becomes overstable and its nose does not turn downward as it passes the summit of the trajectory and follows the descending branch. In such cases the projectile is said to have overspin or overstabilization ... 

Equations (13.89) and (13.91) describe the projectile trajectories of a volcanic bomb for linear drag. 

The factors which influence the shape of the trajectory of a specified projectile after it leaves the launching device are principally the earth s gravitational field and the characteristics of the air thru which the projectile passes. The design of the projectile and the methods used to stabilize it have a considerable effect on the trajectory. For example, the rotation imparted to a projectile by the rifling in the gun causes it to move...

A proper description of the dynamics in a collision is required to obtain stopping cross sections that compare well with experimental results over a wide range of projectile energies and that include all the channels available during the collision. Here we have shown that the END approach fulfills this requirement. The proper inclusion of non-adiabatic effects, even at the minimal level of END, provides trajectories for the projectile suitable for the calculation of scattering problems. We have... 

Having in mind this idea and assuming a straight-line trajectory of the projectile, the energy loss in ion-atom collision as a function of the impact parameter b can be written as... 

When an ion approaches a metal surface, the energy associated to its motion perpendicular to the surface determines whether it will penetrate the solid or it will be reflected at the top-most atomic layer. If one wants to obtain information about the structure of the surface, the trajectories of interest aie those for which the particle interacts for a long duration with the metal surface before it is reflected. This situation is achieved by using projectiles... 

Coriolis effect - The deviation from simple trajectories when a mechanical system is described in a rotating coordinate system. It affects the motion of projectiles on the earth and in molecular spectroscopy leads to an important interaction between the rotational and vibrational motions. The effect may be described by an additional term in the equations of motion, called the Coriolis force. 

However, equation (24) assumes that the probability is independent of the trajectory of the projectile. In order to incorporate interference effects, one introduces into equation (16) the electronic wave function Up). Thus, projecting the final wave function onto a final state f) and repeating the Schiff procedure, one obtains...

As mentioned earlier the trajectory of the liquid jet before and after the CBL is of importance for design purposes. As we will see, it is also a critical piece of information needed by some empirical-numerical models to simulate the atomization process. A considerable number of research studies have been merely focused on measurements and predictions of the jet trajectory and its variation with change in different parameters such as the pressure and the temperature. To develop a simple model for predicting the jet trajectory, we can think of the jet as a stack of thin cylindrical elements piled on top of each other to form a jet. One such element with infinitesimal thickness h is shown in Fig. 29.1b. Then, one can treat the motion of the element like that of a projectile moving up with initial y-direction velocity j and zero x-direction velocity. In the simplest approximation, the only force acting on the element is the aerodynamic drag force...
