Mark the statement true (T) or false (F).For a particle moving with a constant velocity, the distance- time graph is a straight line.

Mark the statement true (T) or false (F): A particle starts from rest under the action of a constant force. The graph of distance versus time is a straight line.

Knowledge Check

  • A particle is moving along a straight line.

    A
    If the acceleration of the particle is more than that of another object, the particle is moving faster.
    B
    If the acceleration is positive, the speed must be increasing.
    C
    If the acceleration and the velocity have the same sign, the speed must be increasing.
    D
    If the acceleration is zero, the velocity is constant but the speed may be changing.

  • A : The area under acceleration - time graph is equal to velocity of object. R : For an object moving with constant acceleration, position - time graph is a straight line.

    B
    If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).
    C
    If Assertion is true statement but Reason is false, then mark (3).
    D
    If both Assertion and Reason are false statement, then mark (4).
