### When velocity is changing what is happening to the slope on a position versus time graph?

The slope of the position/time graph is the magnitude of
velocity, i.e. speed.
It doesn't tell you anything about the direction of
velocity. If the direction of
velocity is changing, the slope of the graph doesn't necessarily
change.
If the magnitude of velocity (speed) changes, then the slope of
the graph changes.
If speeding up, the slope of the graph increases, and the graph
curves upward.
If slowing down, the slope of the graph decreases, and the graph
curves downward.
