However, by making a few assumptions about what happens to the kinetic energy of an impactor after it strikes a surface and by applying dimensional analysis, we can come up with a simple model for how crater diameter scales with the kinetic energy of the impactor.$K=\frac{1}{2}mv^2$$m$$v$$M$$V$$d^3$$M \pr…
