Question
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
-
- 0 + 0
- + 0 + +
- 0 0
The correct answer is:
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
