Inkling: Water Vs Rock

By themselves, water and rocks do not move. When an external force acts on them, it causes them to move. When you push a rock, you are exerting a force on it. When that rock is pushed against a piece of glass, we all know what happens.

When you push a rock at water, the water swallows the rock.

When you push water at rock, water may carry the rock away, or even break it. Look at waves smashing away cliffs over time, or the power of tsunamis sweeping away everything in their paths.

Maybe being rigid or relaxed (fluid) is just like rock and water: they are a medium for transmitting force.
