_Description:_ Tracker allows you to extract motion data from a video, so by simply taking a video of a classroom demonstration, students can clearly visualize concepts like acceleration, parabolic motion, periodic/pendulum motion, and momentum conversation in collisions. Tacker makes it much easier to communicate counter-intuitive concepts by enabling students to slow down and quantify the motion of objects in videos. _Examples of uses:_ * Demonstrating constant acceleration due to gravity * Confirming conservation of momentum in elastic collisions * Showing that projectile motion is parabolic
