Historical tidbits. 1776: Laplace suggests four mechanisms that could explain secular perturbations of Moon-Earth orbit. One the explanations was a non-instantaneous propagation of gravity, affecting the binary system (abandoned because its speed would be too large to be measurable to explain the effect). .

Free electrons + Anisotropy = Polarization. The History of Polarization in Cosmology: . Energy associated with forces that depend on the position or configuration of a body. Objects acquire potential energy when work is done on it. As an object loses potential energy, it can do work. Potential energy is the capacity to do work even if not doing work yet. Learning Objectives. I can mathematically rearrange the potential energy equation.. I can calculate Potential Energy using the formula.. Gravitational Potential Energy (GPE). Potential Energy that depends upon an objects height above a reference point. Ravi . kumar. . Kopparapu. Center for Gravitational-Wave Physics (CGWP) . Gravity.
