  • Newton and +ve work in cyclic motion

    I'm not a biomechanist, per se, but I have used biomechanice
    in my work and appreciate it as a discipline. I have a sneaking suspicion
    that there are a few biomechanists out there
    who don't
    understand properly the basic physics of their discipline.

    eg at a conference once I witnessed the following overhead presented in an
    almost reverent way:

    F=ma (Winter, 1979)

    Admittedly the paper was based on a masters' thesis but the day someone
    presented one of Newton's laws and attributed it to Winter (1979) is still
    discussed in ergo circles here.
    The masters' topic by the way was on biomechanics and being supervised by
    a biomechanist.

    If there are biomechanists out there who don't know there mechanics and
    dynamics that well what does this say about those who taught them and
    those they teach?
