A velocity-time graph shows how an object's velocity or speed changes over time. The y axis represents velocity (v), while the x axis represents time (t). In the graph for constant velocity, the line remains horizontal, showing that the velocity of the object does not change over time. In the graph for constant acceleration, the line slopes upwards, showing that the velocity of the object increases over time. This increase in velocity is called acceleration. In the graph for constant retardation, the line slopes downwards, which means that velocity decreases over time. This decrease is called retardation. Retardation can also be called negative acceleration or deceleration. A moving object can both accelerate and decelerate. In the graph for irregular motion, the line moves up and down. This means that the velocity of object increases and decreases several times. | 0.298928 |

But as populations increase and re- sources become less available, rates of growth slow down and slowly level off, reaching the carrying capacity.
