Some aspects of linear motion are more easily seen on velocity-time graphs than on position-time graphs, and some are more visible on position-time graph than on velocity-time graphs. Therefore, it is ...

This says that the acceleration will be the slope of the velocity-time graph and the velocity will be the slope of the position-time graph. But in this case we are going backwards.

You can see this in a graph of position vs. time for that bullet. Oh, you can also notice the missing data when the bullet passed in front of the black parts of the background. But how off is it?

The velocity at a particular instant is equal to the slope of the tangent drawn on position-time graph at that instant. 3.Average acceleration is the change in velocity divided by the time ...
