Abstract
This research aimed to study for time-dependent angular displacement angular velocity and tension force of particle mass mk in the pendulum motion under air-resistance force and time-dependent external force 2 type. We can use the time-dependent external force 2 type in calculate the time-dependent angular displacement angular velocity and tension force of particle mass mk in the pendulum motion. The time-dependent external force 2 type is f0sin(wfat) and f0sin2(wfat). This research, we can use Newton's law of motion to calculate the time-dependent angular displacement and the time-dependent angular velocity and the time-dependent tension force in polar coordinate. We can use the method of solving inhomogeneous second order differential equations by the parameter variation method. The work in this research compares the time-dependent angular displacement, the time-dependent angular velocity and the tension force that depends on two external forces. Research results: A pendulum motion subjected to an external force of type f0sin2(wfat) will cause the time-dependent angular displacement, the time-dependent angular velocity and the tension force in the string oscillates more up and down overall than a pendulum motion subjected to an external force, type f0sin(wfat).
