The path of an artillery shell is not a parabola, but an ellipse.
** News to Sir Isaac Newton and all his admirers for the last 300
years
or so.
( neglecting air resistance of course).
The parabola is an approximation; the equation of motion that defines
a parabola assumes that all the gravitational force is always in the
same direction (ie, horiz velocity constant, vertical velocity =
V0 -
kt^2) But in reality, the gravity vector points at the center of the
earth, so changes in direction as the shell moves, and that's not a
parabola any more.
** How typically pedantic to the point of bizarre.
The path is one curve or it's the other. It's math, not pedantry.
** YOU are the pedant.
" Pedantry can also be an indication of certain developmental disorders.
In
particular those with Asperger Syndrome,
orHigher Functioning Autism, often have behaviour characterized by
pedantic
speech.[1] Those with Asperger's tend to
obsess over the minutiae of subjects, and are prone to giving long
detailed
expositions, and the related corrections, and
may gravitate to careers in academia or science where such obsessive
attention to detail is often rewarded."

Piss off.
Why haven't you bothered to argue based on the physics?
** Because extreme pedantry is the real issue.
Fuckhead.
