Keyframe Animation

Typically, the animation begins at one extreme position, and as gravity and inertia act on it, the pendulum accelerates toward the center and decelerates as it swings to the other side, creating a repeating motion.
Use the graph editor to adjust the acceleration and deceleration, ensuring the motion follows natural physical principles, particularly with “ease-in” and “ease-out” when the pendulum swings.

By previewing the animation, I can observe the delayed motion of the weight. The weight lags behind the top part of the chain as the pendulum swings. As the speed changes, the weight’s swing amplitude and the chain’s angle will vary.
Focus on the follow-through and drag effects to ensure that the movement between the chain and the weight feels realistic.

Use the graph editor to further refine the speed curves, making the swinging motion smoother.
If necessary, I add more pendulums or move the top hanging point to simulate more complex pendulum movements. For example, when the hanging point moves, the weight will continue to swing, following the movement naturally.
