Conservation of Energy
... Use the meter stick taped to the right door frame in the video for scaling purposes. Translate the origin to the lowest position marked in any frame so that the floor will be the zero reference point for potential energy. Plots of position-time, velocity-time, and acceleration-time are useful. ...
