The investigations of forces in playground are analogous to the investigations in amusement park pendulum rides, although bringing equipment along is less problematic on a playground. Experiments involving energy transformations are impossible to perform in amusement rides, and playground swings also offer more possibilities to study factors influencing the period.

• Forces in swings
• Periodic motion of a pendulum
• Energy transformations in swings
