gravitational potential energy

[‚grav·ə′tā·shən·əl pə¦ten·chəl ′en·ər·jē]
(mechanics)
The energy that a system of particles has by virtue of their positions, equal to the work that must be done against gravitational forces to assemble the particles from some reference configuration, such as mutually infinite separation. Also known as gravitational energy.

The fundamental concept behind this demonstration, replacement of the mean electrostatic binding potential in a real liquid by a gravitational potential energy well, is realized by milling a depression into the center of a flat aluminum disk (refer again to Fig.
In (4), the minus sign means that gravitational potential energy has a positive correlation with the particle size.
In the present study the total mechanical energy of the athlete was calculated as the sum of the kinetic energy and gravitational potential energy of the athlete's centre of mass.
It therefore has less gravitational potential energy after the bounce.
In contrast to the IP model, the SLIP model predicts that forward kinetic and gravitational potential energy fluctuate in phase.
When approximating the total potential energy U only with the local gravitational potential energy Gm[M.sub.[direct sum]]/r, Eq.
The taller the ramp, the more gravitational potential energy Shaun will store at the top of it.
In order for the cluster to be gravitationally stable, Zwicky knew, the cluster's gravitational potential energy had to equal half the kinetic energy of all of its individual galaxies.
As the train climbs, it gains gravitational potential energy.
The stellar core's iron-peak nuclei decompose into those of helium, which then fragment into neutrons at the price of the star's gravitational potential energy. The core collapses, producing a neutron star - a degenerate ball of neutrons somewhat akin to a white dwarf, but far, far denser.
