When a space shuttle travels in a circular orbit around Earth, is a force required to maintain its high speed? If suddenly the force of gravity were cut off, what type of path would the shuttle follow?

No force in the direction of the shuttle’s motion exists. The shuttle “coasts” by its own inertia. The only force acting on it is the force of gravity, which acts at right angles to its motion (toward Earth’s center). We’ll see later that this right-angled force holds the shuttle in a circular path. If it were cut off, the shuttle would move in a straight-line path at constant speed (constant velocity).
