Energy Skatepark Challenge

I did the first challenge for this extension. Which made me think "What does it mean when we say energy is conserved." Energy that is conserved can be explained multiple ways in this situation. The TME bar on the right side of the bar graph stays the same throughout the time the skater is on the track. On the curve graph, It shows that the KE and PE repeat itself throughout. They never go higher than the TME. Whenever the KE is low and PE is high, TME stays the same. Vice versa with TME being the same. But throughout the skaters ride, the TME never changes which shows that energy is conserved.
