Perturbation
The path of one heavenly body moving around another due to gravitational attraction is an orbit. Orbits can be elliptical, circular, or parabolic, depending on the speed and direction of the moving body. This motion is governed by Newton's law of universal gravitation.
When objects are bound gravitationally in centrifugal motion, the objects are said to be in orbit of each other.
Aristotle's predictions of heavenly motion were qualitative rather than quantitative. He described the motion of celestial bodies in terms of natural qualities and tendencies, such as uniform circular motion and the hierarchy of elements. Aristotle's model focused on understanding the causes and explanations behind celestial phenomena rather than precise numerical measurements.
In planetary terms, when referring to the motion of planets and moons etc. the motion is describes as orbiting. Moons are on orbit around planets, while the planets are in orbit around the sun. An orbital motion.
Plato proposed that all heavenly motion is uniform and circular because he believed that perfect, immutable forms governed the universe. The circle was considered the most perfect shape because it has no beginning or end, representing eternity. By applying circular motion to the heavens, Plato aimed to reflect the divine and unchanging nature of the cosmos.
Disturbance in particle motion parallel to the wave velocity is called a longitudinal wave. Disturbance in particle motion perpendicular to the wave velocity is called a transverse wave.
motion
The disturbance traveled from one end to the other end in a medium without the acutal moment of particle is called wave motion.
Qualitative
So they don't fall out of the sky.
qualitative
Aristotle's predictions of heavenly motion were qualitative rather than quantitative. He described the motion of celestial bodies in terms of their natural behavior and relationships rather than using mathematical equations or measurements.
Most waves derive their energy and motion from disturbances in a medium, such as air or water, that propagate through it. This disturbance creates a transfer of energy from one point to another, causing the wave to travel.
Wave is nothing but the disturbance being transferred. So wave speed is the distance covered by the disturbance in one second
A wave in which the disturbance of the medium is in the same direction as the wave motion is called a longitudinal wave. In longitudinal waves, the particles of the medium oscillate back and forth in the direction of the wave propagation. Examples of longitudinal waves include sound waves in air and seismic waves in the Earth.
The path of one heavenly body moving around another due to gravitational attraction is an orbit. Orbits can be elliptical, circular, or parabolic, depending on the speed and direction of the moving body. This motion is governed by Newton's law of universal gravitation.
A motion described in relation to a frame of reference is called relative motion. This refers to the motion of an object in relation to another object or observer, taking into account their respective speeds and positions.
