This summer my friends and I went to maunawili falls in Kailua. This is a natural water fall where you can jump off into a pretty deep pond. First we had to hike into the trail and finally we found it by following the stream up the mountain. It was tons of fun. Okay so when you get there you can jump off from different heights ranging from 40 to 10 feet. I went to the top one. When i was standing on the rocks i had all potential energy and no kinetic energy. Once my foot left the cliff and i jumped out toward the pond i began to lose potential energy and gain kinetic energy. there was no energy lost but it was being transfered from potential to kinetic energy. The equation for kinetic energy is KE=1/2mv^2 and the equation for potential energy is PE=mgh.
