What I'm here to find out: I am in the early stages of a physics project to build a electric circuit or use an electrical source to power the force that will carry a marble throughout the mechanical portion of the project, going through linear acceleration and circular motion. I'm not sure what...

Oh okay, so we can't assume that S is 2.5 even if it looks like it is in center between H and C. So if the total distance is 5, we can't just divide it by 2 and say that S is at 2.5? It is 2 miles distance but even if it would be 4-5 in terms of C being 0, would it also be considered negative...

Oh, that makes sense, that may be the case. Usually when you hear origin, you think that it is the starting place. Well, in that case, how would you be able to calculate the position of Sandra? If she goes to her home, then it is a negative displacement. The distance between S and H is 2 and if...

If Sandra is in the center and the origin was the mall, then mall = x0. If she walks home, she is walking from the origin to home, right? So shouldn't that be -5? Even if she started from the center, it should be -3 or something?

Hi, I just joined Physics Forum and wanted to say hello, so hi. I just began studying physics this year and I'm not sure if I've understood the concepts properly...so it would be helpful to get those explanations here.

Homework Statement H------S-----C Sandra is represented by S, Home is represented by H, and C is represented by commercial mall. If Sandra walks home, what is her displacement if the commercial mall is the origin? The distance between H and S is 2 miles and the distance between S and C is...
