For example, if the acceleration is zero, then the velocity-time graph is a horizontal line - having a slope of zero. Velocity is the rate at which position changes, so the position v. -time graphs are displayed in Figure 4. Here time taken is plotted along the x-axis and velocity acquired is plotted along the y-axis we know that displacement of an object is the product of velocity and time i. Displacement time graph, velocity time graph and acceleration time graph are explained here. Acceleration-time graphs tell us about an object’s velocity the same way velocity vs time graphs tell us about an object’s displacement. The instantaneous velocity can be defined as the slope of the tangent line to the arc at any spot on a displacement-time (x vs. If the acceleration is positive, then the line is an upward sloping line - having a positive slope.
