Final answer:
The orbital speed of a satellite in a circular orbit is related to its mass.
Step-by-step explanation:
The orbital speed of a satellite in a circular orbit is related to its mass. The relationship between the orbital speed and the mass of the satellite can be explained using Newton's second law of motion. According to this law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In the case of a satellite in a circular orbit, the centripetal force required to keep the satellite in its orbit is provided by the gravitational force between the satellite and the Earth. Therefore, the orbital speed of the satellite depends on its mass.
