NEET Physics Circular Motion Dynamics MCQ Question
Which of the following statements regarding circular motion dynamics is correct?
Centripetal force is directed away from the center of the circular path.
The acceleration of an object in circular motion is always directed towards the center.
Centripetal force can be provided by gravitational force in planetary motion.
The velocity of an object in uniform circular motion changes in magnitude but not in direction.
Correct Answer
Detailed Explanation
In circular motion, the acceleration is given by v²/R, and it always points toward the center of the circle, as stated in the context. Centripetal force is necessary for this acceleration, demonstrating its central role in maintaining circular motion.
