Day 75: Ramp n’ Roll
College-Prep Physics: Ramp n’ Roll is a fun Java applet that lets you adjust the heights of the ramps, starting position of the ball, and initial position of the ball. Then it animates the motion along with the graphs of position, velocity, and acceleration. I’ve used it as formative assessment — give the class a ramp set-up and ask them to predict the velocity-time graph.

Many thanks to NSTA’s Lab Out Loud for hosting the applet!
