uniform circular motion वाक्य

उदाहरण वाक्य

1. Plato proposed that the seemingly chaotic wandering motions of the planets could be explained by combinations of uniform circular motions centered on a spherical Earth, apparently a novel idea in the 4th century.
2. Eudoxus of Cnidus, who worked with Plato, developed a less mythical, more mathematical explanation of the planets'motion based on Plato's dictum stating that all phenomena in the heavens can be explained with uniform circular motion.
3. Consistent with the first law, the time derivative of the momentum is non-zero when the momentum changes direction, even if there is no change in its magnitude; such is the case with uniform circular motion.
4. This violated one of the fundamental principles of Aristotelian cosmology namely, that the motions of the planets should be explained in terms of uniform circular motion, and was considered a serious defect by many medieval astronomers.
5. However, in the years following publication of " de Revolutionibus ", for leading astronomers such as Erasmus Reinhold, the key attraction of Copernicus's ideas was that they reinstated the idea of uniform circular motion for the planets.
6. Using these coordinates, the motion along the path is viewed as a succession of circular paths of ever-changing center, and at each position " s " constitutes non-uniform circular motion at that position with radius " ? ".
7. For example, the centripetal force exerted " inwards " by a string on a ball in uniform circular motion " sideways " constrains the ball to circular motion restricting its movement away from the center of the circle.
8. Whereas Greek astronomers expressed " prejudice in favor of circles or spheres rotating with uniform motion ", such a preference did not exist for Babylonian astronomers, for whom uniform circular motion was never a requirement for planetary orbits.
9. Thanks to his examination of the meticulous observations compiled by astronomer Tycho Brahe, Kepler " was the first to understand the nature of the departures from uniform circular motion that had puzzled astronomers since the time of Plato ."
10. The equant solved the last major problem of accounting for the anomalistic motion of the planets but was believed by some to compromise the principles of the ancient Greek philosopher / astronomers, namely uniform circular motion about the Earth.
