    Assertion : A body may be accelerated even when it is moving uniformly. Reason : When direction of motion of the body is changing then body may have acceleration

    Can the motion of a body be accelerated even when it is moving unifromly ?

    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

    Assertion: If a body is momentarily at rest, it means that force or acceleration are necessarily zero at that instant. Reason: Force on a body at a given time is determined by the direction of motin only.

    Assertion: A body having non zero acceleration can have a constant velocity. Reason: Acceleration is the rate of change of velocity.
