  • The Gravitational Energy Formula is Wrong (2005) [Updated 1 decade ago]

    The formula for gravitational potential energy is GPE=-GMm/r. The gravitational potential energy of a one-kilogram body on the surface of the Earth is negative 62,501,800 joules. The gravitational potential energy of a one-kilogram body at a height of ten meters is negative 62,501,700 joules. Minus 62,501,700 is a less negative number than minus 62,501,800, so raising a body to a height causes its gravitational potential energy to go up. As a body falls to the ground, kinetic energy goes up, gravitational potential energy goes down, and energy is conserved. So far, so good. The gravitational potential energy of a two-kilogram body on the surface of the Earth is negative 125,003,600 joules. Minus 62,501,800 is a less negative number than minus 125,003,600, so a one-kilogram body has more gravitational potential energy than a two kilogram body. False! The gravitational potential energy formula is obviously wrong. You can read my paper My Gravity Theory Is Better Than Your Gravity Theory on my web page http://www.danielzimmer.com/
