Physics SVAT Applet
To plot position, velocity, and time graphs for an object, first enter the initial position and velocity.
Then, enter a list of what the acceleration is in each time period, separated by spaces.
Finally, enter a list of how long each time period is, again separated by spaces.
In the "plot" box, you can enter any combination of S, V, A, and T (T controls whether the dashed red lines are drawn).
