One velocity will be positive, and the velocity in the other direction will be negative. The vertical axis of a velocity-time graph is the velocity of the object and the horizontal axis is the time taken from the start. Features of the graphs. When an object is moving with a constant velocity, the line on the graph is horizontal. When an object is moving with a steadily increasing velocity, or a steadily decreasing velocity, the line on the graph is straight, but sloped. The diagram shows some typical lines on a velocity-time graph. Speed - time graph The steeper the line, the more rapidly the velocity of the object is changing.
