Matrices

All photos taken on a Panasonic Lumix GX1 with an aperture of 16, exposure time of 15 seconds, and a distance of 12 inches between the top end of the pendulum and the lens.

We identified unique positions on the perimeter of the tray and tested both a perpendicular and a tangential push.

For the first two trays, we did three trials of each set-up in order to determine how consistent the outputs were.

The last set is missing the tests at 4 weights because the camera ran out of battery.
