Okay, I started thinking about relativity earlier, and got stuck on how to square speed. I went with some basics to try and figure it out, this is some of what i came up with; Main Question: Does (10mph)^2 equal? A. 10 m^2 per h^2 B. 100 m^2 per h^2 C. 100 mph Logically "B." makes sense, except for the fact that it seems to be measuring the acceleration of size? oh, on a slightly different note, how do you calculate the potential energy of an object?
