I'm wondering if there exists any utility on the web which displays $x$-$t$, $v$-$t$, and $a$-$t$ graphs for, say, a number of well considered example animations. The utility should allow pausing, rewinding, replaying, and 'stepping' through the animation. When playing the animation, it should 'highlight' the current time on the d,v, and a graphs.
Etc etc. I'm sure you have an idea what I'm after - searches online have mostly led me to lectures and lessons explaining the relationship between the three graphs.
