orbital revolution वाक्य

The orbital angular momentum operator is the quantum-mechanical counterpart to the classical angular momentum of orbital revolution : it arises when a particle executes a rotating or twisting trajectory ( such as when an electron orbits a nucleus ).
A "'sub-orbital spaceflight "'is a spaceflight in which the spacecraft reaches space, but its trajectory intersects the atmosphere or surface of the gravitating body from which it was launched, so that it does not complete one orbital revolution.
While revolution is often used as a synonym for rotation, in many fields, particularly astronomy and related fields, revolution, often referred to as orbital revolution for clarity, is used when one body moves around another while rotation is used to mean the movement around an axis.
In a theory known as the Harmony of the Spheres, Pythagoras proposed that the Sun, Moon and planets all emit their own unique hum based on their orbital revolution, and that the quality of life on Earth reflects the tenor of celestial sounds which are physically imperceptible to the human ear . }}
