Grid cells and physics reasoning. In the room of classical mechanics there are objects a rectangle with mass then velocity then momentum then p=m*v, another with kinetic energy, mass, velocity, E=0.5*m*v^2, and so on. To solve a problem we must create a bridge from given to desired quantity.

How high does a ball thrown upward at velocity V goes?

energy is conserved

initial energy 0.5*m*v^2

energy at top mgh

mgh=0.5*m*v^2

using bridges in the math algebra room

h=(0.5*v^2)/g

It is not reasoning, it is more like playing dominoes. Simple find, move and match.
