NEET Physics Uniform Circular Motion MCQ Question
Which of the following statements about uniform circular motion are correct?
The velocity of an object in uniform circular motion is constant in magnitude but changes in direction.
Centripetal acceleration acts outward from the center of the circular path.
The displacement of an object after one complete revolution is zero.
The speed of an object in uniform circular motion can vary while moving along the circular path.
Correct Answer
Detailed Explanation
In uniform circular motion, the speed remains constant while the direction changes, leading to a constant magnitude of velocity. The centripetal acceleration always points towards the center, not outward. The displacement after one complete revolution is zero because the object returns to the starting point. The speed does not vary in uniform circular motion.
