Short Answer

Draw a free body diagram for a satellite in an elliptical orbit showing why its speed increases as it approaches its parent body and decreases as it moves away

The power of attraction between the satellite and the parent body is determined by the square of their distance.

Step by Step Solution

Step 1: Definition of Satellite

A satellite is an item that is placed into orbit on purpose.

Step 2: Determining why the speed of the satellite increases

The following is a free body diagram of a satellite in an elliptical orbit:

The centripetal force is FC, and the satellite's velocity is v.

The system's overall angular momentum is retained since there is no exterior force acting on it.

The centripetal force of attraction allows moving the satellite in an elliptical orbit. The power of attraction between the satellite and the parent body is determined by the square of their distance. The velocity of the satellite’s movement in an elliptical orbit increases as the distance between the parent body and satellite decreases and vice versa.
