NEET Physics Speed & Velocity MCQ Question
Which of the following statements about speed and velocity are correct?
Instantaneous speed is equal to the magnitude of instantaneous velocity at that instant.
Average speed can be less than average velocity in all cases.
For uniform motion, instantaneous velocity is different from average velocity.
Both average speed and average velocity can be used to describe motion over finite time intervals.
Correct Answer
Detailed Explanation
Statement A is correct as instantaneous speed is defined as the magnitude of instantaneous velocity. Statement B is incorrect because average speed is always greater than or equal to average velocity. Statement C is incorrect because for uniform motion, instantaneous velocity equals average velocity. Statement D is correct as both can be used to describe motion, but their values will differ.
