Homework Help: Concept Question. Record turntable rotates at constant angular velocity.

  1. Apr 11, 2010 #1
    1. The problem statement, all variables and given/known data
    Suppose a record turntable rotates at constant angular velocity.
    a) Does a point on the rim have radial and/or tangential acceleration?
    b) If the turntable's angular velocity increases uniformly, does the point have radial and/or tangential acceleration?
    c) For which cases would the magnitude of either of the components of linear acceleration change?


    2. Relevant equations
    ?


    3. The attempt at a solution
    Basically, I don't understand the concepts, but I think for part b) that it has both radial and tangential acceleration... but I'm not certain
