In both of the snippets I saw, they were talking about a debris field for a meteor that breaks up. In these fields, the larger chunks of the meteorite are further down in the field. Why is this? Let me approach this first from a terminal velocity view. This requires a model for air resistance. I will use the following: Where: rho is the density of air A is the cross sectional area of the object C is a drag coefficient that depends on the shape of the object v is the…
