Complete the passage to describe velocity vs time graphs.

A velocity vs time graph is a graph that shows the relationship between the velocity of an object over time.
is plotted on the x-axis in seconds, and the
of the object is plotted on the y-axis in meters per second.

The shape of a velocity vs time graph can provide valuable information about the motion of an object. A flat line indicates that the object is moving at a constant velocity. A straight diagonal line represents uniform acceleration or deceleration. A curve or nonlinear line suggests that the object is accelerating or decelerating at a changing rate. The area under the graph represents the displacement of the object over a certain time interval. By analyzing the slope of the graph at different points, one can determine the acceleration of the object at each moment in time. Velocity vs time graphs are essential tools for studying the motion of objects and understanding the changes in velocity over time.
