3. The gravitational field of a stationary body
Cosmic body creates around itself a force field – the gravitational field. The main characteristic is its gravitational strength tension at any point. It characterizes the force which acts on a point located in this different body. The tension is given by:
g = F / m, (2)
where g – the field strength (tension), F – gravitational force, m – mass of the test body made to the field.
The gravitational field can be described analytically by calculating it's intensity for each point of the field or graphically, causing tension in the plot line or field lines. An example of a graphic image of the gravitational field is shown in Figure 2. Power lines or tension lines (1) begin at cosmic body (2) and extend into the surrounding space according to the formula (2) to infinity. When interacted many bodies the line tension can take a curved shape and then on the graph the field strength can be characterized by density of the location of power lines.
