For an object in motion with constant acceleration in a plane, what is the shape of its path if the initial velocity is
If the initial velocity is zero, the object moves under constant acceleration alone, resulting in a straight-line path along the direction of the acceleration vector. This is a special case of rectilinear motion. As per NCERT Chapter 3, equations v=u+at, s=ut+½at², v²=u²+2as describe uniformly accelerated motion. Applying correct signs and units gives Straight line as the result, so option C is correct.
