Position–Time → Velocity–Time

Draw any position–time graph in the top canvas with your mouse. Then click Compute Velocity to see an approximate velocity–time graph below.

Position vs Time

Horizontal axis: time  |  Vertical axis: position
Draw with mouse (click & drag)

Velocity vs Time

Horizontal axis: time  |  Vertical axis: velocity
Resulting velocity–time graph
Hint: A straight, increasing line in position–time should give a constant (flat) velocity line.
