Whether a moon, a planet, or some man-made satellite, every satellite's motion is governed by the same physics principles and described by the same mathematical equations. A Satellite is a Projectile. The fundamental principle to be understood concerning satellites is that a satellite is a projectile. That is to say, a satellite is an object ...
Kepler’s Laws of Planetary Motion. Kepler's First Law. The orbit of each planet about the Sun is an ellipse with the Sun at one focus. Figure \ (\PageIndex {1}\): (a) An ellipse is a closed curve such that the sum of the distances from a point on the curve to the two foci \ ( (f_1 and f_2) \) is a constant.
May 27, 2024 · The study of satellite orbital motion is a complex and dynamic field that combines principles of physics, mathematics, and engineering. From the basic kinematics of motion to the intricate effects of orbital perturbations and Earth’s irregular shape, each aspect plays a vital role in the successful deployment and operation of satellites.
Apr 10, 2022 · To illustrate how a satellite is launched, imagine a gun firing a bullet horizontally from the top of a high mountain, as in Figure 3.5.1 3.5. 1, which has been adapted from a similar diagram by Newton. Imagine, further, that the friction of the air could be removed and that nothing gets in the bullet’s way. Then the only force that acts on ...
Kepler’s Second Law. Each planet moves so that an imaginary line drawn from the Sun to the planet sweeps out equal areas in equal times (see Figure 2). Kepler’s Third Law. The ratio of the squares of the periods of any two planets about the Sun is equal to the ratio of the cubes of their average distances from the Sun.

The conditions are satisfied, to good approximation, by Earth’s satellites (including the Moon), by objects orbiting the Sun, and by the satellites of other planets. Historically, planets were studied first, and there is a classical set of three laws, called Kepler’s laws of planetary motion, that describe the orbits of all bodies satisfying the two previous conditions (not just planets in ...
