In the single pendulum, the relation between the period and angle of motion according to the string length and the weight is understood and the gravitational acceleration value is measured. The frequency at which the resonance condition occurs according to the weight of the pendulum and the length of the string is measured and compared with the theoretical value. In addition, you can observe how the resonance condition changes in the double pendulum and confirm the energy conservation law with the measurement of changing the kinetic energy to the potential energy.
