In 3D animation, the movement of one part of the object affects the movement of another part of the chain reaction, especially in the pendulum animation, there are also more movements such as the tail bounce. This means that the end part will have a lag with the main control end, which is what we need to deal with in the animation process, such as soft seaweed long hair flowing will have a similar effect.

This picture is my practice assignment, in which the teacher pointed out my shortcomings to me. The degree of my following movement is not strong enough, and it will float in the air due to the effect of inertia. This kind of floating in the air needs to be higher, and the final falling part needs a longer time of slow movement.
