What is centripetal force

It appears to me if the rotating object is tied by some physical means to the center of rotation, the force is towards the center, but if the object is not tied to the center then the force is away from the center. Water in a bucket spinning in a vertical circle, satellites are examples of latter case.
No, in all cases the net force is toward the center. The bucket (and gravity) pushes the water toward the center; gravity pulls the satellite towards the center.
