Conservative forces

The first tenn is tire dipole force, sometimes called tire trapping force, Fj, because it is a conservative force and can be integrated to define a trapping potential for tire atom ... [Pg.2459]

In general, the solution components of the DAE (4) are the correct limits (as K —> oo) of the corresponding slowly varying solution components of the free dynamics only if an additional (conservative) force term is introduced in the constrained system [14, 5]. It turns out [3] that the midpoint method may falsely approximate this correcting force term to zero unless k — 0 e), which leads to a step-size restriction of the same order of magnitude as explicit... [Pg.282]

The usual choice for the weight functions is to make the random force the same as the conservative force ... [Pg.419]

Fortunately we do make contact with reality at times. There are forces for real change in culture so the conservative forces do not always succeed. I have great faith in science as a unique force for... [Pg.254]

This is generally a so-called conservative force and depends only on the position of the body. Second is the frictional force, which always opposes the motion of the body through its medium. This includes sliding friction if the body is slipping across a solid surface. Most relevant is viscous friction due to the drag forces of air, water, or other fluids that retard the motion of any body passing through them. For low velocities, this force is directly... [Pg.40]

But the chemical insurrection he so boldly planned produced an unavoidable reaction. Each escalation organized by Tim and the thousands, even millions, who eventually sympathized with him was faced with an equal and opposite response by the conservative forces in the country who watched what he was doing with mounting alarm. The more Tim praised LSD, the more they trounced it. Tim said it saved souls. They said it promoted suicide and murder. [Pg.19]

The simplest procedure is to take the origin of a global I-frame so that P = 0 and linear momentum conservation forces kj = —k2. At the antipodes, kd = k2 so that the common I-frame is restricted now. The particle model in this frame becomes strongly correlated. If spin quantum state for I-frame, one corresponds to the linear superposition (a /S)[CiC2]i and the other I-frame system should display the state (a P)[c, — Ci]2, namely, an orthogonal quantum state. The quantization of three axes is fixed. Spin and space are correlated in this manner. Now, the label states (a P)[c2 — cji and (a )[C C2]2 present another set of possibilities. This is because quantum states concern possibilities. All of them must be incorporated in a base state set. At this point, classical and quantum-physical descriptions differ radically. The former case handles objects that are characterized by properties, whereas the latter handle objects that are characterized by quantum states sustained by specific materiality. [Pg.80]

In this form there is a close correspondence with the equations of hydrodynamics, or vortex-free flow of a fluid under the influence of conservative forces. Equation (12) resembles a hydrodynamic continuity equation if a2 is considered to be a density and if the stream velocity v = V(j). As V x v = 0,... [Pg.119]

When a body of volume V and area S is under the action of both contact and conservative forces, a balance of forces gives... [Pg.146]

The fluid particles possess several attributes as mass mi, inertia, position ri, translational and angular velocities, v, co, and a force law. The droplets interact with each other by forces dependent on the type of particles. We use the two-body, short-ranged force F as it is postulated in Espan ol(1998). Ttis type of interaction is a sum of conservative force F, two dissipative forces with translational and rotational parts F and F, and a random Brownian forcer that is. [Pg.209]

Thermal effects can be incorporated into the model by adding a thermal random force r(f) and a damping term myv to the conservative force between slider and substrate ... [Pg.202]

Figure 8 illustrates the unstable motion for k < k by showing the evolution of the time-dependent potential energy y(x) associated with the conservative forces, namely,... [Pg.210]

Even though (2) has been obtained under the assumption that solvent fluctuations are close to equilibrium, the Brownian particle system described by it may reach macroscopic states far from thermal equilibrium. Moreover, under (finite) shear, this holds generally because the friction force from the solvent in (2) cannot be derived from a conservative force field. It has non-vanishing curl, and thus the stationary distribution function F describing the probability of the particle positions r, cannot be of Boltzmann-Gibbs type [47]. [Pg.65]

For conservative forces, which can be derived from a potential d> being independent of time, the terms reduce to... [Pg.46]

A particular class of forces, known as conservative forces, can be expressed as the gradient of a scalar potential energy function (or potential) denoted by Ep ... [Pg.195]

For a system placed in a conservative force field an alternative form of the equations of motion is obtained by introducing a Lagrangian function defined as the difference between the kinetic energy, T(q, q), and the potential energy, Ep (, t) ... [Pg.197]

A.5.1 A conservative system is one in which the energy of a point in state space is related to its position. Gravity and electrical potential are both examples of conservative forces. [Pg.26]

The generalisation, to two bodies in a plane, moving under conservative forces, which also gives the equations for the relative motion in the general problem of three bodies in a plane, is... [Pg.87]

The system evolves with the innermost orbit receding from the central body (because of the non-conservative forces acting on mi) up to the moment where the system is captured into a resonance, a2 is almost constant. When the 2/f-resonance is reached, the system is trapped by the resonance. As known since Laplace, after the capture, mi continuously transfers one fraction of the energy that it is getting from the non-conservative source to m2, so that 02 also increases. One may note from Figure 9 that, after the capture into the resonance, ai increases at a smaller pace than before the capture. The increase of the semi-major axes is such that the ratio ai/a2 remains constant. [Pg.283]
