NEETPhysicsMotion in One Dimension

Assertion : On a curved path, average speed of a particle can never be equal to average velocity. Reason : Average speed is total distance travelled divided by total time. Whereas average velocity is final velocity, plus initial velocity divided by two.

Options

  1. AIf both Assertion and Reason are correct and Reason is the correct explanation of Assertion
  2. BIf both Assertion and Reason are correct but Reason is not the correct explanation of Assertion
  3. CIf Assertion is true but Reason is false
  4. DIf Assertion is false but Reason is true

Correct answer

C. If Assertion is true but Reason is false

Step-by-step solution

Assertion is true: On a curved path, the displacement (a straight line from start to end) is always less than the distance traveled along the curve. Since average velocity = displacement/time and average speed = distance/time, and time is the same, average speed will be greater than average velocity (unless the path is straight and there's no change in direction, which is not the case for a curved path). Reason is false: Average velocity is total displacement divided by total time, not (final velocity + initial vel
