Are constant acceleration and zero acceleration the same?

Constant acceleration means that the acceleration does not change. Some would say that if the acceleration is zero then the acceleration does not change and so one can say that the acceleration is constant. read more

Zero acceleration means there is no change in velocity i.e. body is moving with same velocity. but constant acceleration means velocity of a body increases or decreases with same rate i.e. by same amount in same time.. read more

Zero acceleration simply means there is no change in velocity with time and no change in velocity means neither its magnitude is changing nor the direction.Whereas constant acceleration say for example g=9.8m/s^2 shows the change in velocity with time (either its speed or direction). read more

If initial velocity is 5 m/sec and acceleration is zero, then the body moves with a constant velocity 5 m/sec. The graph is a horizontal straight line(v=u+at). read more

Zero acceleration is zero. It's different from constant acceleration as the latter means any value >0 or <0 but not equal to 0. From the graph, if there would have been constant acceleration, the graph would have been different. So, although zero is a constant, zero acceleration is zero acceleration, not constant acceleration. read more
