centripetal accelerationProperty of the motion of an object traveling in a circular path. Centripetal describes the force on the object, directed toward the centre of the circle, which causes a constant change in the object's direction and thus its acceleration. The magnitude of centripetal acceleration a is equal to the square of the object's velocity v along the curved path divided by the object's distance r from the centre of the circle, or a = v2/r. 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. How to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit webmaster's page for free fun content. |

| Once the contours have curvature, then the centripetal acceleration must be taken into account. At the high centripetal accelerations present in a hydrocyclone (700m/[S. When you're at the top of the loop, gravity wants to yank you to the ground, but centripetal acceleration makes the train hug the track and inertia pushes you into your seat--even when you're upside down |
