The difference between stillness and relative stillness during the epidemic

The difference is that the reference objects are different. Usually, stationary refers to being stationary relative to the ground, while relative stillness refers to being stationary relative to a certain reference object. This reference object is determined by yourself

There is no way to prove that an object is at absolute rest. Absolutely stationary objects do not exist. Rest is when an object remains in the same position relative to another reference object around it, so it can only be relative movement and relative stillness. Movement and stillness are relative. To determine whether an object is at rest or in motion, an appropriate reference object must be selected. Different reference objects are selected, and the motion state of the object is different. Relative stillness means that two objects move in the same direction and at the same speed, and their positions relative to each other do not change.

We know that everything is composed of molecules. A molecule is a whole composed of atoms that are combined in a certain bonding order and spatial arrangement. A positive atom is composed of a dense nucleus and a number of negatively charged electrons moving at high speed around the nucleus. Therefore, from the perspective of the electrons in the atoms that constitute something itself moving around the atomic nucleus, we can conclude that the constituent parts of something itself are in constant motion. This is absolute motion, so there is no absolute rest. It can only be concluded that one object is relatively stationary compared with another object.
