Answer:
The importance of categorizing a force as being either internal or external is related to the ability of that type of force to change an object's total mechanical energy when it does work upon an object. When net work is done upon an object by an external force, the total mechanical energy (KE + PE) of that object is changed.

Tầm quan trọng của việc phân loại một lực là bên trong hoặc bên ngoài có liên quan đến khả năng của loại lực đó để thay đổi tổng năng lượng cơ học của một vật thể khi nó hoạt động trên một vật thể. Khi công việc ròng được thực hiện trên một đối tượng bởi một ngoại lực, tổng năng lượng cơ học (KE + PE) của đối tượng đó được thay đổi.

Answer:
The Sun
Explanation:
The sun does not move or rotate and hence cannot retrograde, however the other planets rotate. Some astronomers define retrograde motion as the Westward movement of the planets relative to the sun, based on this definition, all the planets experience retrograde movement. On the other hand, while some astronomers define retrograde motion as the movement that the other planets make when earth passes them while orbiting the sun. Based on this second classification, Mercury and Venus do not retrograde relative to the earth because they move faster than the earth.
