Just for clarity's sake, with a trapezoid histogram I mean something like that: stmary.ws/highschool/physics/home/notes/kinematics/equation/… | |

| Dec 4, 2013 at 11:14 | comment | added | AstoundingJB | Just a comment: as @jk88 said, you can't calculate the exact distance travelled if you don't know the exact speed at each time. Nevertheless, from your data, you can get an approximation, via the trapezoid histogram I told. This approx corresponds with taking a constant acceleration between each steps, that is assuming a linearly varying speed. | |
