Centripetal force is a force directed toward a fixed center that keeps an object moving along a circular path. In orbits, it is provided by gravitational forces.
Kepler's Laws of Planetary Motion: These laws describe how planets move in elliptical orbits around stars. They provide insights into various aspects such as orbital shape, speed, and time taken for one complete orbit.
A geostationary orbit is when a satellite orbits Earth at an altitude where its orbital period matches Earth's rotation period. This allows the satellite to appear stationary relative to an observer on Earth.
