Under what conditions (s) is the magnitude of average velocity of an object equal to its average speed ?

Text Solution

Verified by Experts

The correct Answer is:
When a body move along a straight line

Knowledge Check

  • Assertion: The average velocity of a particle is zero in a time interval. It is possible that the instantaneous acceleration is never zero in the interval. Reason: The magnitude of average velocity in an interval is equal to its average speed in that interval.

    A
    If both assertion `&` Reason are True `&` the Reason is a corrrect explanation of the Asserion.
    B
    If both Assertion `&` Reason are True but Reason is not correct explanation of the Assertion.
    C
    If Assertion is Trie but the Reason is False.
    D
    If both Assertion `&` Reason are false

  • Statement-2: It is possible when the direction of motion keeps changing. Statement-1: Magnitude of average velocity is equal to average speed, if velocity is constant.

    A
    Statement -1 is true, Statement-2 is true, Statement-2 is a correct explanation for statement -1
    B
    Statement-1 is true, Statement-2 is true, Statement-2 is not a correct explanation for statement-1
    C
    Statement-1 is true, Statement-2 is false
    D
    Statement-1 is false, Statement-2 is true
