Welcome to PF.
Ep is the potential energy of the mass and it is on the Y-axis, right? And the graph is crossing above 0 on the Y-axis? Then you are getting an output energy that is
your input energy. This would be because the weight hits the ground with kinetic energy: you aren't converting all of the potential energy to rotational energy in the flywheel.
Thats correct. So does that mean that because the mass still has kinetic energy when it hits the floor, some is converted into sound etc and not all into rotational energy of the flywheel?
