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 ...

This shows the horizontal acceleration of the pod as a function of time ... Question 1: Sketch a graph of velocity vs. time and another graph for position vs. time for this same trip.

the slope of a velocity-time graph will be the acceleration of the car. Notice that I have fit four linear functions to the data (I included the fitting equation for one of these linear fits).
