Pendulum within a car.

  1. Apr 15, 2012 #1
    1. The problem statement, all variables and given/known data

    If we attach a pendulum to the roof of a car and drive the car in a circle, why does the circle swing outwards away from the center of the circle.

    2. Relevant equations



    3. The attempt at a solution

    I don't understand the idea that inertia causes this, can some 1 clarify this for me.

    Same idea of swinging a mass at the end of a string, what keeps the mass at the end of the string, I dont understand the idea of "centripetal force". In quotations because I know its not really a force.

    What keeps the mass at the end of the string? The string does. The object is trying to move in a straight line, but the string is causing a constant acceleration towards the center of the circle.

    Though what about the pendulum in the car.
