Loop The Loop Track, 1 Each

The Loop The Loop Track by United Scientific is a physics demonstration apparatus that shows centripetal acceleration and the conversion of potential energy into kinetic energy. A metal ramp with a vertical loop sits on a sturdy base with rubber feet, and a net at the end of the loop catches the ball. It includes 16 mm and 19 mm steel balls plus an activity guide, and is used by physics teachers in middle school, high school and introductory college labs.
