This lab can be used to investigate the relationship between velocity and the height above ground. We use it when studying potential and kinetic energy.

The lab is based on Scratchy, the roller coaster riding cat. Clicking one of the numbered buttons at the bottom of the screen launches Scratchy. Scratchy's motion is on an coordinate plane. You can observe Scratchy's position and the elapsed time in the lower left corner of the screen. This information can be recorded in a table like this:
