An object is moving in a straight line. The velocity time graph is as

1.	An object is moving in a straight line. The velocity time graph is as shown below. Then (1) In part OA acceleration is increasing. (2) In part AB acceleration is increasing. (3) In part OA acceleration is decreasing.(4) In part AB acceleration is decreasing.
Answer» (4) In part AB acceleration is decreasing. As slope of v–t graph is decreasing between points A and B. So acceleration is decreasing.
