If the argument of perigee is zero, meaning that perigee and apogee lie in the equatorial plane, then the ground track of the satellite will appear the same above and below the equator (i.e., it will exhibit 180° rotational symmetry about the orbital nodes.) If the argument of perigee is non-zero, however, the satellite will behave differently ...
Ground arms: Servicemen bring their rifles to the ground. Trail arms: Servicemen bring their grip from the pistol grip to the carrying handle of the rifle in order to carry the rifle horizontally; Sling arms: If the soldiers have a "sling" (strap) on their rifles, then this command can be called.

A (bipedal) gait cycle is the time period or sequence of events or movements during locomotion in which one foot contacts the ground to when that same foot again contacts the ground, and involves propulsion of the centre of gravity in the direction of motion. A gait cycle usually involves co-operative movements of both the left and right legs ...
In television stations, recording studios, and other installations where signal quality is critical, a special signal ground known as a "technical ground" (or "technical earth", "special earth", and "audio earth") is often installed, to prevent ground loops. This is basically the same thing as an AC power ground, but no general appliance ground ...
A ground connection that is missing or of inadequate capacity may not provide the protective functions as intended during a fault in the connected equipment. Extra connections between ground and circuit neutral may result in circulating current in the ground path, stray current introduced in the earth or in a structure, and stray voltage.
A level playing field is a concept about fairness, not that each person has an equal chance to succeed, but that they all play by the same set of rules resulting in formal equality of opportunity. [1] In a game played on a playing field, such as rugby, one team would have an unfair advantage if the field had a slope.
Kneeling is a basic human position where one or both knees touch the ground. It is used as a resting position, during childbirth and as an expression of reverence and submission. While kneeling, the angle between the legs can vary from zero to widely splayed out, flexibility permitting. It is common to kneel with one leg and squat with the ...
