  • Q6
    In an experiment to find the centre of mass of a card shape, why is it important that the card can swing freely?
    Friction may cause the card shape to catch on the plumbline.
    Friction may stop the card shape settling with the centre of mass below the point of suspension.
    Friction may deform the card shape.
    Friction would make it difficult to mark the card with a vertical line.
