Mechanical energy swing because of the work done by the pendulum to oppose these non-conservative forces. That the loss of mechanical energy in a system always resulted in an increase of the system's temperature has been known for a long time, but it was the amateur physicist James Prescott Joule who first experimentally demonstrated how a certain amount of work done against friction resulted in a definite quantity of heat which should be conceived as the random motions of the particles that comprise matter. This equivalence between mechanical energy and heat is especially important when considering colliding objects. In an elastic collision,
Let's Go Fly a Kite on the string of Michael's kite. It is often rumored that Walt Disney had asked his songwriters to write a song about a kite because of his two daughters. Both of his daughters are members of the Kappa Alpha Theta sorority and their symbol is a kite. The song "Let's Go Fly a Kite" is sometimes believed to be dedicated to Kappa Alpha Theta. This has been debunked by multiple sources. On 6 April 2015 a version by Burl Ives featured on BBC's "The One Show". Let's Go Fly a Kite "Let's Go Fly a Kite" is a song from
