The inward force required to keep a satellite moving a circular orbit is?
The earth exerts the necessary centripetal force on an orbiting satellite to keep it moving in a circle at constant speed. Which statement best explains why the speed of the satellite does not change although there is a net force exerted on it?
A satellite is moving in a circular orbit around the earth due to gravitational force. What is the effect on gravitational force and speed if the radius of orbit is reduced?
