Homework Help: Uniform Circular Motion Displacement

  1. Jun 2, 2007 #1
    In uniform circular motion:
    True False Displacement is constant.
    True False Velocity is constant.
    True False Acceleration and velocity are perpendicular.
    True False Speed is constant.
    True False Accleration direction is constant.
    True False Acceleration magnitude is constant.

    My answers are in bold, the computer says its wrong, can anyone steer me in the right direction?

    Thanks :)

    Acceleration is always towards the center of the circle, so its direction is changing as the body moves along the circular path
