G-force diagram on a roller coaster?

[QUOTE="eri139, post: 6190963, member: 653556"] [B]Homework Statement:[/B] So for my physics class, we rode on a roller coaster with our phones to record g-force data in the x, y, and z directions. We recorded the moment we were going up, a moment at the top of the coaster when it was just flat (no change in height, but the coaster was still moving around in a semi-circle shape), and a moment as we were going down. We have to draw the g-force diagram for the roller coaster for all 3 moments. I get force diagrams for 2-d diagrams, with the force of gravity and the normal force and all that, but for 3-d I'm so lost. It also doesn't help that I don't know what the x, y, and z directions are, since I've seen xyz graphs online with the z pointing upwards and others with the y. I used the app Physics Toolbox, by the way. [B]Relevant Equations:[/B] F = ma? So, while we were going up the track, the z-direction gforce seemed to go up. It went from -1 to about -0.6. The x-direction seemed to be around 0, more or less? All x values were under 0.177. The y-direction decreased, more or less, from -0.4 to -0.9. I think if I understand how the force diagram while going up I might be able to handle the rest of the moments we recorded. I think the x direction is supposed to be the roller coaster going directly left or right, which would make the g-force 0, as shown in the data. And I think the force of gravity should decrease with increasing altitude. So would that match up with the y-direction being the upwards direction, since it decreases? Or the z-direction, since it technically increases but the values are negative? And, how would I draw the force diagram? Are there any forces that I would include besides gravitational and the force making the coaster go up? And which directions would all of my forces be acting? Should I draw in Fg with the two different components? How do I do this? Please help, I'm so confused! [/QUOTE]
