I am confused about how to calculate gravity's force (Gs).?

Question

I was researching the vomit comet and how it simulates weightlessness. It follows a path called a Kepler curve (i couldn't find anything on this, but as far as i can tell it is a parabolic shape.) but, basically the plane accelerates downwards and upwards at certain angles to create certain G forces. i was wondering how do you calculate Gs using angles. Ex. the plane accelerating downward at a 45 degree angle versus a 30 degree angle. Thanks for your help!

Answer 1

You don't. To experience 0 g in earth's gravitational field, you have to fly in a parabolic path. Wherever you happen to be on that parabola determines your flight angle. The larger the parabola, the longer you can maintain the condition, but that also takes a higher initial speed. The V/C dives first only to gain some extra speed before pulling up to join its intended parabola.

In real life, the pilot must also reduce the thrust slightly going up and increase it coming down to counter the effects of air drag. This makes sure the zero g condition is true in the fore and aft direction as well as the local up and down direction.

Answer 2

I'm afraid your question makes no sense. The whole objective of the Vomit Comet is to cause a freefall condition within the aircraft. Therefore, the acceleration is simply g, corrected for the altitude. The trajectory of the plane only affects the duration of the controlled freefall

Answer 3

you would be able to desire to apply the equstion G (the gravitational consistent 6.seventy 3 circumstances 10 to the destructive 11) circumstances the 1st mass circumstances the 2nd mass all divided by ability of the gap between them squared.
