## Main Question or Discussion Point

my question is as follows:

when do we need to consider a three dimension body as a point like body in our calclulations?

i mean outside our theoretical/homework practices when should we assume the body as a point like?

one thing i can think of is when the geometric properties of a body is not important and therefore isnt taken into consideration into our calculations.

and maybe also when the body is a particle but other than that i dont know.
