Short Description: Although the mirror sensor card has no pendular motion, it does oscillate from side to side in the horizontal plane. This motion can be studied by students to learn about oscillations in the horizontal plane, as opposed to the pendular oscillation in the vertical plane. Note also that perpendicular forces do not affect each other so although gravity is pulling on the magnet, this force does not disturb the horizontal motion.
