#### Figure shows the graphical variation of displacement with time for the case of a particle moving along a straight line. The accelerations of the particle during the intervals and are respectively

The portion of the graphs is convex upward. It represents negative acceleration. The portion represents negative acceleration. The portion represents that is not changing with time. Clearly, it is a case of zero acceleration. The portion of the graph is concave upward. It represents positive acceleration. The portion is a straight line sloping upward to the right. It represents uniform velocity and hence acceleration is zero
