WHAT'S THAT GRAPH?
Wait for the applet to completely load, then click on Animation 1.

For each animation below, click the animation link, watch the animated picture of the motion, then draw a graph of x vs. t. You can click on the picture to take measurements.
You can afterwards check your graph by clicking the "View Graph" link. Can you write a formula as a model for each motion?
