Explore the fascinating world of geosynchronous satellites in this video. Learn how these communication satellites are strategically placed in circular orbits, staying directly over fixed points on the Earth's equator as our planet rotates. We delve into the physics behind these orbits, calculating the speed and acceleration of a satellite in geosynchronous orbit, using the Earth's radius and altitude as reference. Gain a deeper understanding of the science that enables global communications.
