Circular Motion

  1. Jan 13, 2008 #1
    The answer is as follow:

    -force is needed toward the centre or there is acceleration toward the centre

    -movement to the left/toward A/away from the centre

    -right hand spring (attached to B) has to stretch to provide force

    I understand that centripetal force acts towards the center as stated in the first point of the answer. But I don't know why M moves away from the center and that spring attached to B stretches. Thank you. :)

    Look at it from above. M just "wants" to go straight--until the springs get compressed/stretched and start pulling it towards the center.
