When an object is moving in a circle, but it is not held to the center by a tangible connection like a string, what provides the centripetal force?

1) some force such as friction or gravity.

2) the tendency for the object to move in a straight line.

3) centrifugal force.

4) the angle of the surface the object moves on.

5) the natural tendency to move in a circle.

Like the gravitational field of the earth if the object is the moon or the friction of tires on road if a car in a turn :)
