It can also help you understand what physics you should be using / taking account of.
A metal ball travelling 1m at 3 m/s and I’m pretty confident I can get a good approximation using the basic Newtonian equations.
An irregular shaped object like a Kangaroo travelling 50.000 km at presumably many hundred of meters of per second and I need to think about a lot more! Not least that this kangaroo os travelling about one and a quarter times around the world so the spherical nature of the world needs to be taken into account!
