Study gravitational acceleration with this tool. Tethered Mass and Spring model shows a mass constrained to move in the x-direction by a horizontal rod and connected to a spring of natural length L = 10. One end of the spring is connected to a movable (draggable) ceiling and the other end is connected to the mass. Users can drag the mass along the rod and users can control the height of the ceiling H by dragging which changes the stretch of the spring. The height H, the spring constant k, and the natural length of the spring L can also be adjusted using the sliders at the bottom of the position vs. time graph.
