I was looking at how speed = distance/time. Then i started messing around with negative signs in the equation and it gave me strange things to think about. I can put a negative sign on the top or bottom of the fraction side and I have a negative speed. When I think about traveling at negative speeds across negative distance, that is acceptable as an object driving away from me with the transmission in reverse. But if the negative sign is on the time side of the fraction, I think about that object moving the same as the former object. This messes up my concept of the entropy in the motion of these objects since the latter would have exhaust rushing into the muffler. I looked at each variable equaling the other two, and the various ways a negative sign can change the real life concepts of what is actually happening. In the end I sat there dumb-founded at the significance of the negative sign being on particular sides of the fraction, how it relates to the actual physical processes and why I was taught that where the negative is in a fraction is insignificant. I am new to thinking about science and math and such. Is this a real thing that is considered by physicists and physics students?
