centripetal acceleration

[‚sen′trip·əd·əl ik‚sel·ə′rā·shən]
(mechanics)
The radial component of the acceleration of a particle or object moving around a circle, which can be shown to be directed toward the center of the circle. Also known as radial acceleration.

If the vehicles do not collide, (i) the distance is stationary, which is a necessary condition for closest approach, if and only if ((16a), (16b)) the relative velocity (9b) is orthogonal to the relative position (8) [equivalent to] (10); (ii) a sufficient condition for closest approach, which is that the distance is minimum, is that the relative acceleration (19a) satisfies (19b) implying that the centripetal acceleration associated with the relative curvature of the trajectories predominates over the relative acceleration projected on the relative velocity.
They report that high centripetal accelerations induce large body forces on the high-density cold reactants and hot, low-density products.
Its results were corrected for gravitational time dilation and centripetal acceleration time dilation, the latter correction clearly showing that acceleration has an impact on special relativity.
It described that the steering was stable, when the centripetal acceleration of the fully loaded train was not more than 0.4g.
Contrarily, for large loading strip lengths, the inertial forces of moving system greatly affect the dynamic behavior of the bridge, especially with the contributions arising from Coriolis acceleration and centripetal acceleration (Table 1); as a consequence, the maximum amplification is observed in the high range of speeds.
However, we know that the vector [S.sub.2] has the same magnitude as [S.sub.1] but set in the opposite direction, and thus, the actions at point B, under the acceleration of [S.sub.2] toward its nothingness are the same as the actions of the point A but in the opposite direction, therefore B produces on A a centripetal acceleration ([b.sub.2]) and a normal acceleration ([b.sub.1]).
It was found that the inclusion of Coriolis and centripetal accelerations leads to the result that the medium behaves dispersive and anisotropic [3].
At first, the target is moving in constant velocity along the x-axis, the initial velocity is 450 m/s, the target is moving in circular accelerated motion from the 51st scan cycle, and centripetal acceleration is 20 m/s.
