Question description

Go to a playground and swing on one of the swings. Try pumping at different rates . Observe whether the rate at which you pump or are pushed affects how easily the amplitude of the vibration increases. Are some rates more effective at building your amplitude than others? You should find that the pushes are most effective when they match the swings natural frequency. Explain how your results support the statement that reasonance works best when the frequency of the applied force matches the systems natural frequency.
