Saturn
12
Which of the following illustrates the concept of centripetal force?
Is a force the makes objects move in straight lines.
Is a force that makes a body follow a curved path.
Is a force in which a smaller body acts on a larger body.
Is a force that is directed away from a center of rotation.
13
