Mythbusters Watermelon Energy Video

To test the law of conservation of energy, here's a little demo. Remember that one energy can neither be created nor destroyed. So let's see in action. First, we have a watermelon about to be launched on a one way trip vertically. Before it heads off on an almost certain journey to a catastrophic destruction, the researcher measures the melons temperature. Then he pitches the melon onto the sidewalk below. Finally, our melon measurer finds the temperature of the melon. The bar once left of it, to see if anything's changed. Is the result of this catastrophic fall that? The melon has lost heat, it's remained exactly the same. Or it's warmed up. Got the answer? Well, it's the last option. Mangling the melon has actually heated it. Energy can never be created nor destroyed. So in this case, the kinetic energy or the falling motion of the melon has to go somewhere, some on to noise, the rest into heat. Okay, a round of applause for science. This is another example to demonstrate the same law. Move and stop your hands quickly, kinetic energy again, they make noise and they get warmer. Proof that energy never gets destroyed, but transferred from one state to another.
