NEETPhysicsMotion in One Dimension

Assertion : Magnitude of average velocity is equal to average speed, if velocity is constant. Reason : If velocity is constant, then there in no change in the direction of motion.

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

A. If both Assertion and Reason are correct and Reason is the correct explanation of Assertion

Step-by-step solution

Assertion is correct: If velocity is constant, it means both its magnitude (speed) and direction are constant. In this case, the distance traveled is equal to the magnitude of the displacement, and thus, average speed (total distance/total time) will be equal to the magnitude of average velocity (magnitude of total displacement/total time). Reason is correct: Constant velocity implies that the object is moving in a straight line without changing its direction. This is why the distance equals the magnitude of the di
