**What is the speed of a geostationary satellite?**A geostationary satellite orbits the Earth at a speed that allows it to remain in a fixed position relative to the surface. This speed is approximately 3.07 kilometers per second (about 11,070 kilometers per hour or 6,878 miles per hour). These satellites orbit at an altitude of approximately 35,786 kilometers (22,236 miles) above the equator. By maintaining both this altitude and speed, the satellite’s orbital period matches the Earth's rotation, enabling it to stay over the same geographic location. If a satellite is placed in **geostationary orbit**, then it has an orbital period \( T \) that is equal to exactly one day. This is useful for communications satellites and weather satellites, since these satellites will appear to occupy a fixed point in the sky (as viewed from Earth's surface).

Central Force

Central force is the force that acts along the center of mass of one body to the center of mass of another body. Its direction from or away from a point on a body to another is called the center of the force. Such forces include gravitational force between two massive objects or electrostatic forces between two charged particles. So from atoms to planets, the central forces play an important role in shaping our daily lives. One of the remarkable features of central forces is that they are conservative, i.e. the total energy of a central force system can always be expressed as a gradient of a potential energy function.
