Mechanical energy nonconservative forces, like frictional forces, will be present, but often they are of negligible values and the mechanical energy's being constant can therefore be a useful approximation. In elastic collisions, the mechanical energy is conserved but in inelastic collisions, some mechanical energy is converted into heat. The equivalence between lost mechanical energy (dissipation) and an increase in temperature was discovered by James Prescott Joule. Many devices are used to convert mechanical energy to or from other forms of energy, e.g. an electric motor converts electrical energy to mechanical energy, an electric generator converts mechanical energy into electrical energy and a
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
