Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating ...

time and another graph for position vs. time for this same trip ... graph should be continuous - that would make the middle velocity constant (zero slope) and non-zero (so that it matches up ...

The velocity-time and acceleration-time graphs for common motions are shown below. For the constant positive velocity graphs and the constant positive acceleration graphs, the initial displacement ...
