Angular/Tangential Acceleration

  1. Apr 5, 2013 #1
    A wheel is turning about its fixed axis at constant speed. Compare the tangential and angular accelerations of a point on a wheel.
    This was a multiple choice question on my exam, which I got wrong... (annoying 8% loss)

    I thought only the angular acceleration would be zero since the speed is constant, but I guess snot.

    a) Both are zero
    b) Neither is zero
    c) Only the angular acceleration is zero
    d) Only the tangential acceleration is zero

    I assume that both are zero, but I'm not sure.

    How are tangential and angular accelerations related to each other?
