Question
Why are pushes given to a playground swing more effective if they are given at certain, regular intervals than if they are given at random positions in the swing's cycle?
Step 1

Two children are on adjacent playground swings with chains of the same length. They are given pushes by an adult and then left to swing. Assuming that each child on a swing can be treated as a simple pendulum and that friction is negligible, which child takes the longer time for one complete swing (has a longer period)? a) the bigger child b) the lighter child c) neither child d) the child given the bigger push
Is the time required to swing to and fro (the period) on a playground swing longer or shorter when you stand rather than sit? Explain.
