Okay, so imagine there is a invisible substance called aether that surrounds us. Aetheric mechanics is the study of how this substance can help explain things that we can see and touch in the world. It's kind of like a puzzle, where we try to fit the aether into different parts of the puzzle to make sense of how everything works.
For example, imagine you have a toy car. You can see it move, but how does it move? Aetheric mechanics might try to explain that the car moves because tiny particles in the aether push against the car and make it go.
Aetheric mechanics can also help explain other things, like why magnets stick together, or why some materials conduct electricity better than others. Scientists study aetheric mechanics to try to understand more about how the world works and how we can use that knowledge to make things better.
It's important to remember that aetheric mechanics is just one of many ways that scientists try to understand the world around us. There are still many mysteries and unanswered questions, but studying aether can help us piece together some of the puzzle.
