A 1000-kg satellite orbits the Earth in a circular orbit at an altitude of 1000 km. The Earths mass is 6.0 X 10^24 kg, and its radius is 6.4 X 10^6 m. -How does the force of gravity on the satellite compare with the centripetal force on the satellite? What is the magnitude of the force of gravity acting on the satellite? -What is the magnitude of the satellites tangential velocity? -What is the gravitational potential energy of the satellite? -What is the value of the acceleration due to gravity at this altitude?
