It is the calculation difference between the height at the ceiling and the 1.2M from which the ball hangs. In laymans terms, there is more potential energy the further form the point of impact rather than closer, up to a point of diminishing return, such as an arrow shot from a bow to a distant target. The actual potential energy differential from 2.8 M to 3.0 M is probably infitesimal, given the small weight and potential density of the ball.
