Physics-Uniform Circular Motion
NEET Physics Uniform Circular Motion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Which of the following statements about uniform circular motion is correct?
A
The acceleration in uniform circular motion is directed towards the center of the circle.
B
The speed of an object in uniform circular motion continuously increases.
C
An object in uniform circular motion travels in a straight line.
D
The angular speed of an object does not relate to its linear velocity.
Correct Answer
Option A
Detailed Explanation
In uniform circular motion, the acceleration is always directed towards the center of the circle, which is a defining characteristic of this type of motion. This is supported by the statement that the magnitude of acceleration is given by a_c = v²/R, with its direction towards the center.
