A teardrop loop helps equally distribute the forces around the loop, as you end up slowing down as you crest, so it will get tighter as it goes up. In a circular loop, there is A: Ejector airtime at the top and B: Increased, and possible dangerous, G-Forces at the bottom of the loop.
A circle is an ellipse, so it's elliptical either way.However, the orbit of Mars is not a perfect circle.
No the planet's orbits are not VERY elliptical but yes, they are somewhat elliptical. They are not just rotating in a circle. More like an oval.
Mars has the most elliptical orbit. The earth's is almost a perfect circle
Planets circle in an elliptical orbit around the Sun.
No, all the planetary orbits are elliptical.
Variable, as an ellipse is not a perfect circle.
An elliptical base is a base that is shaped like a flattened circle. This is most common on objects that are cone shaped.
About the same shape as an egg, or oblong. Not a perfect circle.
No, because all planets known have elliptical orbits.
it looks like a circle seen slightly on edge
Nothing is perfect.
It's an orbit that is not a perfect circle, it has some elongation to it.
