    Statement I: An object can possess acceleration even at a time when it has uniform speed statement II: It is possible when the direction of momtion keeps changing.

    Statement-I : A positive acceleration can be associated with a 'slowing down' of the body. Statement-II : The origin and the positive direction of an axis are a matter of choice.

    Assertion : An object may have acceleration even if it is moving with uniform velocity Reason : An object may be moving with uniform velocity but it may be changing its direction of motion
