we just spoke about acceleration.  A = Velocity/Time.

It Doesn't Make Sense To Me In This Way

konradzuse · Answer

It shows you the velocity on the left, and the time on the bottom...  Where the dots are corrispondes to the velocity/time.

anonymous · Answer

If you look at the graph, you will see that on the x-axis is time, and on the y-axis is the velocity. First, are you familiar with derivatives of functions?

anonymous · Answer

Well, remember that the acceleration is a measure of how much the velocity changes in time. Looking at point A you see that at that specific point, the velocity does not change in time (the slope of the graph is zero). You can imagine this by taking a point veery close to the left of A, and a point veery close to the right of A. If you look at the change in velocity between those two points close to A, you can see that it is zero. The same applies to point B :)
