The Circle of Life

So these past few weeks we have been learning about energy, work, and power.  And of all places that i thought about physics was during Lip Sync.  This year the seniors did a clip from Lion King's The Circle of Life.  We came up with the funny idea of having one of the senior boys lifting a smaller senior boy resembling when Rafiki presented Simba to the animal kingdom.  So during lip sync, Keahi was able to successfully lift Marc in the air for about five seconds.  As Kehai did this, he had no net work because there was no change in kenetic energy due to gravity acting in an equal and opposite way, but he did increase Marc's potential energy.  And since there was not net work, there was no way to find Keahi's power.
