Kinetic energy

Earth science; Mapping science

The capacity of a system for doing work by virtue of the velocities of the various moving masses in the system. The kinetic energy (k. E. ) of a body of mass M moving with velocity v is ½ M v 2. ...

Earth-centered ellipsoid

Earth science; Mapping science

An ellipsoid representing the Earth, having its centre at the Earth's centre of mass, and having its minor axis coincident with the Earth's axis of rotation.

Astronomic equator

Earth science; Mapping science

That line, on the surface of the Earth, on which the astronomic latitude at every point is 0 o . Also termed the terrestrial equator and frequently written the Equator. Because of the deflection ...

Normal ellipsoid

Earth science; Mapping science

(1) An ellipsoid which is at a specified, constant gravity potential and which envelopes but rotates with the Earth. (2) An ellipsoid on which gravity is given by a standard gravity formula and ...

Angular elevation

Earth science; Mapping science

The angle, at a point, between the horizontal plane through that point and a line from the point to a designated object or in a designated direction. It is also called altitude, angular altitude, ...
