    An object oscillates with simple harmonic motion. The graph shows how the displacement of the object varies with time.

    A displacement–time graph for an oscillator. The curve is a cosine shape, starting at maximum positive displacement at time zero and continuing over two full cycles.

    Which graph shows how the velocity of the object varies with time?

    Four velocity–time graphs labelled A to D. Graph A is an inverted sine curve starting at zero and then peaking at a negative maximum. Graph B is a sine curve starting at zero and then peaking at a positive maximum. Graph C is a cosine curve starting at a positive maximum, identical to the given displacement-time curve. Graph D is an inverted cosine curve starting at a negative maximum.

        An object oscillates with simple harmonic motion. The graph shows how the displacement of the object varies with time.

        A displacement–time graph for an oscillator. The curve is a cosine shape, starting at maximum positive displacement at time zero and continuing over two full cycles.

        Which graph shows how the kinetic energy of the object varies with time?

        Four kinetic energy–time graphs labelled A to D. Graph A is a positive-only curve starting at zero and showing two peaks. Graph B is an inverted sine curve that starts at zero, then peaks at a negative maximum, and completes two full cycles. Graph C is a positive-only curve starting at zero and showing four peaks. Graph D is a sine curve that starts at zero, then peaks at a positive maximum, and completes four full cycles.
