NEET Physics Speed & Velocity MCQ Question
What is the relationship between average speed and average velocity over a finite interval of time?
Average speed is always less than or equal to average velocity.
Average speed is always greater than or equal to average velocity.
Average speed equals average velocity in all cases.
Average speed can be less than average velocity depending on direction.
Correct Answer
Detailed Explanation
Average speed is defined as the total path length divided by the time interval, while average velocity is the displacement divided by the same time interval. The average speed is always greater than or equal to the magnitude of average velocity, with equality occurring only when the motion is in a straight line without any change in direction.
