What is closed orbits and describe about it?
In physics, a closed orbit refers to the path of an object, such as a planet, satellite, or particle, that repeatedly follows the same trajectory in a periodic manner, returning to its starting point after a fixed period of time. This type of motion is also referred to as periodic motion or oscillatory motion.
The motion of an object in a closed orbit is governed by a central force, such as gravity, which causes the object to move in a curved path around a central point. The curvature of the path depends on the strength of the force and the initial velocity of the object. If the force is strong enough and the velocity is just right, the object will move in a circular or elliptical path, and will continue to do so indefinitely.
For example, the moon's orbit around the Earth is a closed orbit. The gravitational force between the moon and the Earth causes the moon to move in a curved path around the Earth, following the same trajectory in a periodic manner. The moon's orbit is not perfectly circular, but is instead an ellipse, with the Earth located at one of the foci of the ellipse. The period of the moon's orbit is about 27.3 days, which means that it takes the moon 27.3 days to complete one orbit around the Earth.
Another example of a closed orbit is the orbit of a satellite around the Earth. Satellites in low Earth orbit typically have a period of about 90 minutes, while those in geostationary orbit have a period of 24 hours, which is the same as the rotation period of the Earth.
