Question

which of the following best describes centrifugal force?
a it is the acceleration experienced by an object toward the center of the circle at the same time.

b it is the force perpendicular to the centripetal acceleration and tangential to the velocity.

c it is the force experienced by an object moving in a circle or along a circular path.

d it is the force acting upon an object that causes it to deviate from its straight-line path, accelerate inward, and move along a circular path.

Explanation:

• Option A: Describes centripetal acceleration, not centrifugal force. Eliminate.
• Option B: Centrifugal force is a fictitious force in a rotating frame, and the description here is incorrect. Eliminate.
• Option C: Centrifugal force is the apparent force experienced by an object in a circular motion (in a non - inertial frame), and this option's description matches the general understanding of centrifugal force as a force related to circular motion.
• Option D: Describes centripetal force, which causes circular motion by pulling inward. Eliminate.

Answer:

C. It is the force experienced by an object moving in a circle or along a circular path.
