What is the role of centripetal force in circular motion?

• It is a force that always acts outward from the center of rotation.

• It is the net force acting in the inward direction, causing circular motion.

• It is a new fundamental force that appears only during circular motion.

• It is the force that opposes the acceleration of an object in a circle.

Which statement accurately describes centripetal force?

• It is a unique, independently defined force like gravity or tension.

• It is always equal to the force of static friction.

• It is the sum of other forces acting in the inward direction.

• It is a force that only exists in the absence of other forces.

How should centripetal force be represented in a free-body diagram?

• It should be drawn as a separate force vector pointing towards the center.

• It should be drawn as a separate force vector pointing away from the center.

• It is never explicitly drawn in a free-body diagram.

• It is represented by the largest force acting on the object.

When analyzing forces in circular motion, what is the convention for the inward direction?

• The inward direction is always considered negative.

• The inward direction is always considered positive.

• The inward direction can be positive or negative depending on the object's velocity.

• The inward direction is irrelevant; only tangential forces matter.
