## Energy 2

Motion (velocity) is caused and changed by acceleration, which is caused by forces, which is caused by interactions with their momentum. What, then, causes interactions?…

## Interaction 2

Forces is the cause of motion changes. But what is the cause of forces? It turns out that interaction is the answer. No forces exist…

## Rotation 2

We can think of two types of motion in this world: motion along a path (the Motion discipline), let’s call it linear motion, and motion…

The ‘how tough’ and ‘how strong’
