Apparatus for Determining "g" During the Free Fall of Bodies
Product Code : JL-GLE-11211
The Apparatus for Determining "g" During the Free Fall of Bodies, SKU JL-GLE-11211, supplied by JaincoLab, measures the acceleration due to gravity. A small magnet holds a steel ball at the start position; releasing it opens a contact that starts a digital timer, and the ball stops the timer when it strikes the contact plate below. From the drop height and the fall time, students calculate g.
