follow-through-overlapping

Nothing stops all at once. When a character halts, their hair keeps moving. When a car brakes, passengers lurch forward. Follow through and overlapping action capture how different parts of a system respond to forces at different rates—the principle that makes animation feel physically grounded.

Follow Through: When the main body stops, appendages continue moving due to momentum, then settle. The termination behavior of motion.

Overlapping Action: Different parts move at different rates throughout motion, not just at stops. Hair doesn't start moving when the head starts—it drags behind, then catches up. The continuous offset of timing.

在對多部分物件、角色附屬物、織物、頭髮或任何需要真實阻力、動量和沈降行為的運動進行動畫處理時使用。 來源：dylantarre/animation-principles。
